Description

Take the following instance:
<a>
<b>
<c>
<d/>
</c>
</b>
</a>

And make a transformation with the following stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
Should Return:b1,c2 =
<xsl:for-each select="/descendant-or-self::/descendant-or-self::[ (local-name()='b' and position()=1) or (local-name()='c' and position()=3)]">
<xsl:value-of select="concat(local-name(), position())"/>,</xsl:for-each>
Should Return: b =
<xsl:value-of select="local-name(/descendant-or-self::/descendant-or-self::[ (local-name()='b' and position()=1) or (local-name()='c' and position()=3)])"/>
Should Return: 4=
<xsl:value-of select="count(/descendant-or-self::/descendant-or-self::)"/>
</xsl:template>
</xsl:stylesheet>

The result should be (which it is when using xsltc):
Should Return:b1,c2 =
b1,c2,
Should Return: b =
b
Should Return: 4=
4

But the result is:
Should Return:b1,c2 =
c1,b2,
Should Return: b =
c
Should Return: 4=
10

It looks like the descendant-or-self::/descendant-or-self:: isn't sorted and that the nodes returned from the iterator isn't unique (e.g. that the iterator believes it returns unique nodes).
