[~martin.honnen],
At this moment, I'm able to provide a workaround XSLT stylesheet for this issue
as follows,
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="3.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/*">
<distinct-values-of-name>
<xsl:variable name="inpSeq" select="for $elem1 in * return
name($elem1)"/>
<xsl:value-of select="distinct-values($inpSeq)"/>
</distinct-values-of-name>
</xsl:template>
</xsl:stylesheet>
The above mentioned XSLT stylesheet produces following XML document
transformation result,
<?xml version="1.0" encoding="UTF-8"?><distinct-values-of-name>p
html:p</distinct-values-of-name>
At this moment, XalanJ's XPath 3.1 processor on this dev branch, doesn't
support parse and evaluation of XPath expression of form */name() (i.e,
currently, XPath function name as XPath step is not supported).
