Pull request overview

Adds regression coverage and adjusts XSLT/XPath/DOM handling to correctly process and serialize namespaced attributes (and related whitespace/order behaviors), resolving issue #135.

Changes:

• Added a comprehensive test suite covering multiple ways of selecting namespaced attributes (prefix, local-name(), namespace-uri()), plus a call-template ordering regression.
• Updated XSLT processing/serialization to better handle whitespace text nodes and preserve xsl:text whitespace.
• Aligned XPath node namespace property naming (namespaceUri) and updated the bundled XPath subproject.
