To be pedantic, my:f($x) is my:f($x) should always evaluate to true()
in the absence of errors. But that can be taken as read.
No, given
<xsl:function name="f">
<xsl:param name="x"/>
<a/>
</xsl:function>
then
f($x) is f($x)
is defined to be false. Similarly, given
<xsl:variable name="x" as="element()*">
<xsl:for-each select="1 to 5"><a/></xsl:for-each>
</xsl:variable>
then
count($x/.)
is defined to be 5. (The /. causes duplicates to be eliminated: this is to
demonstrate that in this case there are no duplicates).
Certain expressions - including function calls - return distinct results
each time they are evaluated.
