The two monolithic XSD content/identity rules only satisfied the OpenAPIKit
validation idiom at the wrong granularity: no per-constraint removability,
no isolable failing/near-miss tests. Split them into 32 named rules, each
finding tagged at its origin and cached per XSDContext so the walk still
runs once per document (the #101 decision against duplicating XSD's
recursive type resolution still holds). Wired the streaming path's ID/IDREF
and identity checks through the same framework instead of calling the
validators imperatively, and added the unwrapAndLookup combinator the rule
already named as required.
Also includes the mandated repo-wide swiftformat/swiftlint pass.
* fix(xslt): resolve string-form document() against the stylesheet element's base URI
A string-form document() reference resolves against the base URI of the
stylesheet element holding it (XSLT 1.0 12.1). For a declaration in an
included or imported file that is the included file's URI, not the top
stylesheet's, so document('data.xml') (or document('')) in an included file
must resolve against the included file.
The parser already tracked each top-level declaration's source-file base but
discarded it after collection. That base is now carried onto the compiled
templates and global variables, into the runtime context, and through to the
function table, so the document() string form resolves against it. Templates
and globals both carry it, so the rule holds wherever the call appears.
Closes Apache Xalan conformance cases mdocs12 and mdocs13.
* fix(xslt): carry base URI into for-each and sort contexts; keep document('') self-referential
Follow-up to the string-form document() base URI work. Three coverage gaps:
- xsl:for-each and xsl:sort evaluate their body and key expressions in a
context derived from, not equal to, the enclosing template's, so a
document() call there resolved against the empty base when the template came
from an included file. Both now inherit the enclosing context's base URI.
- A non-empty base URI made document('') in the top stylesheet resolve to that
base and route through the loader, rather than returning the stylesheet's own
parsed document as before. The parsed stylesheet is now registered under its
base URI, so document('') reaches it without the loader; document('') in an
included file (a different base) still loads that file.
* fix(xslt): resolve document() references against the correct base URI
The document() function resolved every relative URI reference against the
single global base, so a reference relative to a document that document()
itself had loaded from a subdirectory could not be found. XSLT 1.0 12.1
defines the base per reference: the two-argument form against the second
argument's first node, the node-set form against each reference node's own
document.
Each loaded document now records the URI it came from as its base, and a
relative reference resolves against that base before the loader applies its
own source-document base. The common one-argument string form is unchanged
(its base is empty, deferring to the loader as before).
Closes Apache Xalan conformance cases reluri09, reluri10, reluri11.
* fix(xslt): record base URI for document() fragment selections
A fragment selection (document('x#frag')) is returned as a detached subtree
whose root identity differs from the cached whole-document tree, so its base
URI was not recorded. Using such a node as the base for a relative document()
reference then resolved against the empty base instead of the fragment's
document. Record the base on each fragment subtree's own root through a shared
helper, so baseURI(of:) finds it whichever node the reference is taken from.
An include or import cycle recursed without bound and crashed the
host with a stack overflow, reachable from stylesheet data. The
compile chain tracks the active load chain by resolved href and drops
re-entry, while diamond composition keeps loading both copies with
their own import precedences per 2.6.2. id() builds a per-document
index on first use instead of re-walking the document per call,
matching key(). Cycle and diamond regression tests added.
The XSLT layer's id() follows the XPath definition exactly: only
attributes the source's DTD declares as type ID identify elements
(internal or external subset, via the transform's resolver), and a
document without ID declarations yields the empty set. generate-id()
produces non-empty, distinct identifiers for attribute and namespace
nodes through their identity hash. Lookup implementations move to
XSLTLookups.swift for the file caps. Xalan baseline 131 -> 129.
Same-name xsl:attribute-set declarations merge as ordered definitions
per 7.1.4, each expanding its used sets before its own attributes with
later definitions winning; xsl:copy carries the source element's
in-scope namespace nodes per 7.5; the namespace fixup lets a carried
attribute prefix shadow an inherited binding unless the element's own
name relies on it; the html method minimizes boolean attributes whose
value repeats their name; and external DTDs and entities in the
stylesheet or source resolve through the transform's document loader.
Four unit tests pin the behaviors. Xalan baseline 174 -> 159
(attribset 13 -> 4, copy 12 -> 7).
key() resolves its index against the current node's own document,
built lazily per document root, so keys work inside document() trees;
a node-set use expression indexes the matched node under every
member's string value; and key() results return in document order
regardless of lookup value order. Xalan baseline 187 -> 182.
xsl:number implements all of XSLT 1.0 section 7.7: level
single/multiple/any with count and from matched as patterns through the
match cache, the value expression with the below-one bypass, and the
format-token engine (punctuation, separator and token reuse, zero
padding, alphabetic/roman/Greek sequences, digit grouping). An
unmatched single/multiple count renders empty; level=any always yields
a number. document() now caches per transform so repeated loads of the
same URI return the identical document and generate-id() stays unique
against live nodes (the idkey49 flake). Xalan baseline 557 -> 475
(numbering 84 -> 7).
