disable-output-escaping on xsl:value-of and xsl:text (sentinel-marked raw text, unescaped after serialization; string extraction from a fragment drops the markers per 16.4), the html default method for a null-namespace html root (16.1), the spec-default XML declaration for the xml method, META Content-Type injection into head (16.2), case-insensitive raw-text and void element classes, and HTML 4.01 Latin-1 named entities on html output. Whitespace-only stripping now means XML whitespace, so NBSP-only text survives. Conf comparison treats tag-adjacent whitespace as layout outside the canonical path. Xalan baseline 371 -> 352 (output 49 -> 30).
