I can't see what's wrong here and I suspect the problem might be elsewhere.
One bit of advice, though: type errors are much easier to diagnose if you
declare the types of all your variables and parameters (using the "as"
attribute). This typically results in the error message being reported much
closer to the point where your code is actually wrong.

Subject: [xsl] so how does sum() work?
Hi All,
I'm experiencing a strange (for me) behavior in my XSLT:
This works:
<xsl:for-each select="cdm:classification/cdm:app-domain">
<xsl:call-template name="print-assertion">
<xsl:with-param
name="business-rule">APP-0010</xsl:with-param>
<xsl:with-param name="message">A classification
to a Functional Application Domain must include a percentage
of use greater than
zero. </xsl:with-param>
<xsl:with-param name="result"
select="number(@cdm:percent-of-use) > 0"/>
</xsl:call-template>
</xsl:for-each>
But this produces "required item type of first operand of '/'
is node; supplied value has item type xs:string"
<xsl:call-template name="print-assertion">
<xsl:with-param
name="business-rule">APP-0011</xsl:with-param>
<xsl:with-param name="message">An Application's
percentage of use across all non LOB domain classifications
must be equal to 100%. </xsl:with-param>
<xsl:with-param name="result"
select="sum(cdm:classification/cdm:app-domain/@cdm:percent-of-
use) = 1.0"/>
</xsl:call-template>
I'm using saxon 9B inside oxygen 9.2
Now if I execute
sum(cdm:classification/cdm:app-domain/@cdm:percent-of-use) =
1.0 within oxygen it correctly evaluates to either true or
false, but produces error when executing within my XSLT ...
but only if the result evaluates to false. When the sum of
those attributes does equal 1.0 then no error is generated.
Any ideas?
Thanks in advance
Oh, BTW: I call my print-assertion template maybe 40 times in
my stylesheet and all works well. Its only the sum() that is
causing me grief.
