Hi there, http://www.w3.org/TR/xmlbase/ says this: " In the example below, the base URI of element e2 should be returned as "http://example.org/wine/rosé". <?xml version="1.0"?> <e1 xml:base="http://example.org/wine/"> <e2 xml:base="rosé"/> </e1> " In oXygen 13.2, if I put the text input point after the e2 element and enter base-uri() into the xpath widget, the resulting value is "rosé" when the widget is set to process with XPath 2.0, whereas it is "http://example.org/wine/rosé" when evaluated with XPath 2.0 SA. When I run the following stylesheet against the same input using all three versions of saxon (including HE) built in, I get the full (correct) base URI as output. <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="2.0"> <xsl:output method="text"/> <xsl:template match="/e1/e2"> <xsl:value-of select="base-uri()"/> </xsl:template> </xsl:stylesheet> I think this must be a bug, unless I'm missing a setting somewhere?
