Re: Question for a code example of <xsl:evaluate> in

Thanks Martin,

Severity: fatal
Description: Static error in XPath expression supplied to xsl:evaluate:
Function {http://my.namespace}doSomething#1 not found.

In the target text, among other things there is this:

     $ops := Q {http://my.namespace}doSomething#1 ('myArgument'),

And I have an existing xsl:function:

<xsl:function name="f:doSomething">
    <xsl:param name="pmyArgument" as="xs:string+"/>
.  .  .  .  .  .


Thanks,
Dimitre
