XSLT and XPath questions would be better posted to the following list:

   http://www.mulberrytech.com/xsl/xsl-list

There are a number of subscribers who would enthusiastically respond to 
such questions.

There is also an *excellent* FAQ at:

Yes, by addressing those elements that are matched by the comparison you 
have, and then counting that set.

Yes, you do have to pass the count function a node set.

Try:

   test="count(document($ARCH_LNK_JJ)/Doc/Laes/JudDoc/Ref/@idproducto
                       [contains(.,$producto)]
              )"

The above will address all those attributes whose value contains the given 
variable string, resulting in a node set, which is then counted, and the 
value of the count is non-negative, so a non-zero result is a result 
greater than zero.

I hope this helps.
