Add five well-formedness checks the W3C xmltest suite surfaced: '--' inside
comments (also rejecting the ---> ending), raw '<' in attribute values, the
literal ]]> sequence in character data, attributes not separated by
whitespace, and characters outside the XML Char production in content, each
a located ParseError. The attribute scanners move to EventReaderAttributes
to stay under the type-body cap.
Add the opt-in W3C xmltest runner (XMLTS_ROOT-gated; the suite is never
vendored, James Clark's license permits redistribution only as the unmodified
archive; Foundation is used in this one test file for file access only).
Baseline: valid/sa 118/119, not-wf/sa 93/186 rejected (up from 80), the
remaining 93 carried as an exact known-deviations baseline so progress and
regressions are both visible. The two remaining leniency classes (internal-
subset DTD grammar, entity replacement-text well-formedness) are #120.
