Description

If a Pattern has a StepPattern that specifies the child axis and is followed
by '//', Xalan fails to correctly match nodes to that pattern. For example,
using the following stylesheet

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text"/>
<xsl:template match="root/child::l1//l3">
<xsl:text>Rule root/child::l1//l3; value of matched node: </xsl:text>
<xsl:value-of select='.'/>
</xsl:template>
</xsl:stylesheet>

and the following document

<?xml version="1.0"?>
<root>
<l1>
<l2>
<l3>root-l1-l2-l3</l3>
</l2>
</l1>
</root>

the result should be

Rule root/child::l1//l3; value of matched node: root-l1-l2-l3

but Xalan produces the following.

root-l1-l2-l3

If the StepPattern following the '//' also has a child axis specifier(e.g.,
match="root/child::l1//child::l3", the following error results:
