PureXML.XSLT.transform accepts parameters overriding xsl:param globals by name; xsl:variable globals are never overridable, with parameter names recorded across imports and includes. The conformance runner honors the xalan harness contract, reading <case>.param files (CRLF is one Character in Swift, so the runner splits on newline graphemes, which the param files exposed). Closes #141. Xalan baseline 128 -> 127.
