test="distinct-values($aVal[for $a in .
return normalize-space($oVal)[contains(lower-case(.),lower-case($a))]])
I think you're trying to test whether at least one of the values in $aVal
satisfies some condition.
Firstly, I can't see why you're removing duplicates. If some $x in
distinct-values(X) satisfies a condition, then some $x in X must satisfy the
condition, so removing duplicates is unnecessary work.
So this reduces to
test="exists($aVal[for $a in .
return normalize-space($oVal)[contains(lower-case(.),lower-case($a))]])
But this is still fishy. normalize-space() returns either a string or
nothing (an empty sequence). So it's an odd thing to apply a predicate to. I
think this reduces to
test="exists($aVal[contains(lower-case(normalize-space(.)),
lower-case($a))])"
or if you prefer
test="some $v in $aVal satisfies contains(lower-case(normalize-space($v)),
lower-case($a))"
This isn't precisely equivalent to the meaning of your expression under the
earlier version of the spec, but I suspect it's what you intended. For
example if distinct-values returns a single zero-length string then the EBV
is false, but exists() return true.

Subject: Re: [xsl] error in XSL file when using JAXP
Thanks David and Michael
Okay at least I think I know where the problem is
arising now.
I have a section of code soon after the for-each loop
which tests for the common values present in both the
XML files imported at the start of the XSL.
The lines are:
-----------
<xsl:choose>
<xsl:when test="distinct-values($aVal[for $a in .
return
normalize-space($oVal)[contains(lower-case(.),lower-case($a))]])">
<xsl:variable name="matchingVals"
select="distinct-values($aVal[for $a in . return
normalize-space($oVal)[contains(lower-case(.),lower-case($a))]])"/>
<xsl:if test="not(empty($matchingVals))">
----------
Now the variable $matchingVals does not contain nodes
but common atomic values.
Is there any other way of writing out this test case
so that I can deal with the new version processor
requirements?
Note: $aVal and $oVal are -
----------
////$arch = File1.xml
////$ont = File2.xml
<xsl:variable name="aVal"
select="$arch/SubConcepts/SubConcept/Value"/>
<xsl:for-each select="$ont/SubConcepts/SubConcept">
<xsl:variable name="oVal" select="."/>
---------
Thanks

That is not the line with generating the error

The error means that you have something like
test="zzzz" or ... [zzzzz] and zzz evaluates to a
sequence whose
first item is not a node but is a number or a string
or some other
atomic value. If the sequence doesn't consist of
nodes then to use it
as a boolean in a test it has to consist of a single
item, which is a
boolean value either true or false. If the sequence
is a sequence of
nodes then, as in xpath1 it will count as false if
it is empty and true
otherwise.
