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.
A >> follow-annotation after a pattern (a foreign element name with
optional [ ... ] content) is skipped, chaining and combining with leading
annotations; neither carries schema semantics. Namespace declarations
inside annotations were already dropped by the annotation skipper, so the
RNC compact syntax is now fully covered.
A string literal split with ~ ("a" ~ "b") is the single literal "ab",
the way long values and namespace URIs are wrapped across lines. The fold
applies wherever a string literal is read: value literals and the URIs of
namespace/datatypes/include/external declarations.
A <value> pattern now carries its datatype, so matching compares the
instance and the literal in that type's value space rather than purely
lexically. Numeric and date/time types compare by value (1 equals 01,
1.5 equals 1.50); booleans treat 1/true and 0/false as equal; string and
token compare by their whitespace-normalized lexical form, as before.
Untyped values default to the built-in token type, and a bare string
literal in the compact syntax is token-typed. Durations and binary types
fall under the lexical rule.
The compact-syntax parser now skips [ ... ] documentation/grammar
annotations (balanced over nesting) wherever they may appear, before a
define or before a pattern, and treats div { ... } as transparent
grammar grouping that contributes its defines and start directly. A
define literally named div still parses when assigned. Splits the
name-class and token helpers into a companion file to stay within the
type and file length budget.
The compact-syntax name class * - nameClass now parses as anyName except
the subtracted class (the model already had anyNameExcept). ns:* - name
would need an nsName-except model case and is left as a refinement.
Part of #79
The RNC datatype parameter block xsd:int { minInclusive = "5" } is now
parsed into facets (previously skipped), matching the XML-syntax <param>
support. The facet mapping is shared by both parsers through a new
RelaxNGFacets helper.
Part of #79
A <data type=> pattern now carries a SimpleType (base + facets) rather
than a bare built-in, and its <param name=>value</param> children
populate the facets (minLength, maxLength, length, pattern, min/max
inclusive/exclusive, total/fraction digits), reusing the XSD datatype
facet validation. So a constrained datatype like xsd:string with
minLength rejects too-short values.
datatypeLibrary resolution, typed <value> comparison, and the RNC
datatype parameter blocks remain.
Part of #79
Compile RELAX NG from both syntaxes and across documents:
- A compact-syntax parser (lexer plus recursive descent) produces the same
pattern algebra the XML syntax compiles to. It covers element and attribute
declarations with name classes and namespace resolution, the , | & combinators
and ? * + cardinality, text/empty/notAllowed, list and mixed, datatypes and
value literals, grammars with start and named definitions (= |= &=), nested
grammars, and include/external references.
- The XML-syntax parser gains include (merging another grammar's definitions,
with the include's own nested definitions overriding) and externalRef
(resolving to an external schema's pattern), both through an injected loader.
Both syntaxes reach the loader through a new schemaLoader parameter that
returns nil by default, so compilation never touches the filesystem or network
unless a loader is supplied.
