Raw-output marker resolution and 16.4 stripping run only when the
stylesheet mentions disable-output-escaping, so source text containing
U+E000/U+E001 survives every other transform untouched, and the text
method removes markers without unescaping content that was never
escaped. The pattern-matching function table is built once per
transform instead of per (template, node) membership test, and a dead
variable left in the numbering engine is gone. Eight focused unit
tests cover d-o-e (with the fragment rule and marker safety), CDATA
terminator splitting, simplified syntax, the html default method with
META injection, per-document key(), and attribute-start axes, so the
burn-down behaviors are CI-visible without the opt-in corpus.
The XML declaration precedes the document type declaration; a
public-only doctype is emitted by the html method and ignored by the
xml method, which requires doctype-system; a literal result element
carrying xsl:version compiles as a single match="/" template (the 2.3
simplified syntax); and cdata-section text containing ]]> splits
across section boundaries. Parser entry and Parts move to
XSLTParserEntry.swift for the file caps. Xalan baseline 218 -> 204
(output 34 -> 21).
