6861cd5d62 feat(validation): eduni errata behaviors, 3.3.3 attribute normalization
The eduni sections run with exact classified baselines. Fixes: 3.3.3
CDATA attribute-value normalization (literal whitespace to space before
reference decoding; char-ref whitespace survives; tokenized collapse on
SPACE only); production-68 lenient undeclared entities in content and
attribute values (validity finding, reference kept literal, nothing
fetched); errata E15 (references/comments/PIs/whitespace in EMPTY,
char-ref whitespace as data in element content, double-escape shape
included); errata E2 duplicate enumeration tokens; errata E14
declarations completed inside PE replacements (VC: Proper
Declaration/PE Nesting); NCName ID values; namespace declarations
subject to the every-attribute-declared rule. Reader validity machinery
split to EventReaderValidity for caps.

Closes #127

89cb299201 feat(validation): DTD declaration-level validity constraints
VC Root Element Type (root matches the DOCTYPE name), VC Unique
Element Type Declaration, VC No Duplicate Types in mixed content, VC
One ID per Element Type, VC Notation Attributes and Notation Declared,
VC Attribute Default Legal plus ID Attribute Default, lexical Name
checks for the ID family, and CDATA as character data in element
content. Strict mode adds VC Attribute Value Type (every attribute
declared; namespace declarations exempt). Declaration findings are
computed once at schema build and reported at the document root. Sun
invalid coverage moves from 43/74 to 62/74; the twelve remaining are
all the standalone='yes' family.

82e70679ef feat(validation): 3.3.3 attribute normalization, 4.3.1 text declarations, 4.4.5 PE char-refs
Tokenized (non-CDATA) attribute values normalize before validity
checks, so enumerations, NOTATION lists, and the ID/IDREF table see
collapsed values. External parsed entities lose their leading text
declaration (validated: version optional, encoding required, never
standalone) instead of carrying it into replacement text. Character
references in PE literals expand at declaration time, making the
Appendix D '%zz;' example parse. A PI target inside the DTD subset
must be separated from its data. Sun baselines tighten to not-wf 55/56
and valid 26/28; the two remaining valid failures share one cause
(replacement text with markup is included as character data, filed
separately).

506c502602 refactor(validation): decompose DTD attribute checks into per-constraint rules (#101) 2026-06-09 04:28:03 +02:00
fb31033ce8 feat(dtd): located content-model errors with recovery hints
An element whose children break its content model now names each stray
child outside the model's alphabet individually, and reports a pure
order/count violation once with the allowed elements as a hint, instead
of a single opaque "do not match its content model". Adds an alphabet
extractor to the content-model matcher. This brings DTD to the same
located standard as the XSD, RELAX NG, and Schematron validators, so all
four schema languages give editor-grade diagnostics.

7f1aada240 feat(dtd): conditional sections, notations, NDATA, external parameter entities
Deepen DTD processing in the doctype scanner:

- Conditional sections are processed, not skipped: INCLUDE sections have
  their declarations scanned, IGNORE sections are discarded, the keyword
  may be a parameter-entity reference, and nested sections are handled.
- <!NOTATION> declarations are parsed and stored on DocumentType.
- Unparsed entities (<!ENTITY ... NDATA n>) are parsed and stored with
  their notation, distinct from general entities.
- External parameter entities are loaded through the injected resolver so
  their declarations expand; the default refusing resolver loads nothing,
  keeping XXE closed.
- NOTATION attributes are a distinct type, validated against the declared
  notations (value must be listed and the notation declared).

Tracking unparsed entities also lets ENTITY/ENTITIES attribute values be
validated against the declared NDATA entities, closing the gap left when
#73 could only check name syntax.

Closes #72

a041b8beca feat(dtd): attribute defaulting, tokenized types, value normalization
Complete the DTD attribute handling found in the audit:

- Default and #FIXED attribute values are applied to the parsed tree.
  parseApplyingInternalDTDDefaults returns a tree where every element
  carries the attributes its <!ATTLIST> defaults, so an editor sees the
  same effective attributes a validating processor would.
- NMTOKEN, NMTOKENS, ENTITY, ENTITIES are validated: NMTOKEN(S) must be
  XML name tokens, ENTITY/ENTITIES must be XML names. Previously all fell
  through to unconstrained CDATA.
- DTD default values are normalized per XML 1.0: character and predefined
  entity references are expanded, literal whitespace becomes a space, and
  non-CDATA values are collapsed and trimmed.

ENTITY/ENTITIES check name syntax only; that the named entity is a
declared unparsed entity is not verified, since NDATA entity tracking is
not yet modeled.

Closes #73

89f8ccc95a refactor(validation): migrate DTD validation onto the framework
Slice 3 of #92. The DTD validator's imperative walk becomes declared Validation
values over a DTDSchema document:

- DTDSchema is now just the schema (content models + attribute declarations) and
  serves as the rules' Document context; its validate/walk methods are gone.
- contentModel and attributeDeclarations are Validation<Element, DTDSchema>, so
  every content-model and attribute violation is now located by coding path
  ("... at path: r/a"). undeclaredElement is added only in strict mode.
- identifierIntegrity is a Validation<Node, DTDSchema> gated to the root, doing
  the document-wide ID-uniqueness and IDREF-resolution checks in one pass.
- DTD.validator(strict:) assembles the rule set; validateAgainstInternalDTD runs
  it and returns [ValidationError] instead of [Issue].

A new test pins the located result. Schema (XSD) and Schematron validators still
use Issue and migrate in the following slices.
