Details
For documents supplied in the form of a JAXP Source object, this will normally
be the absolutized value of the SystemId property of the Source object.
For documents read using the XPath doc() or document() functions,
or the XSLT <xsl:source-document> instruction,
it will normally be the absolutized URI that was used to read the document (even if a user-supplied
URIResolver redirected the request to some other URI).
The value can be set programmatically on the TreeInfo for the relevant document tree
using the call node.getTreeInfo().setUserData("saxon:document-uri", URI), where URI is a string.
Setting the value to a zero-length string causes document-uri() to return the empty sequence, ().
