The specification is clear that if two nodes are in different documents,
their relative position in document order is implementation-dependent.

Subject: [xsl] Can I predict the build order of nodes?
I noticed an interesting build order/selection issue between
Saxon and Microsoft XSL transforms ... in my style sheet I have:
<xsl:param name="stylemasterfile">
<xsl:value-of select="/winelist/stylemasterfile"/>
</xsl:param>
<xsl:param name="stylemasterset"
select="document($stylemasterfile)/styles | /winelist/styles"/>
<xsl:variable name="stylemaster" select="$stylemasterset[last()]"/>
The XML may have:
1) a file pointer (in /winelist/stylemasterfile) which
contains <styles>
2) an embedded <styles> (at /winelist/styles)
3) both
If it contains both, the rule should be to select the embedded one.
But selecting $stylemasterset[last()] and testing I noted
that they are in opposite order on the two XSLT transformers
when both exist.
Without saying which is which ... what is the right answer?
What do you think is the proper result of this:
document($stylemasterfile)/styles | /winelist/styles
Internal styles from /winelist/styles
External styles from document($stylemaster)/styles
or
External styles from document($stylemaster)/styles Internal
styles from /winelist/styles
Or does the spec make no determination of order?
