As of now, Xalan doesn't have dedicated XPath 3.1 API, to use Xalan for
XPath 3.1 processing only. The focus has been on XSLT 3.0 implementation
development.

But Xalan may implement such an API.

I think, it may be difficult to modify and introduce new methods within
JAXP XSL interfaces, to allow XPath 3.1 usage. Xalan may have a dedicated
XPath 3.1 API, with Xalan's own API signatures.
