Re: SET-INTERSECTION function/template for sequences

I am trying to implement in XSL a *set-intersection* "function" in the form of a template. It should accepts two sequence parameters and return a sequence parameter. The application for this function will be to argument values that contain space delimited lists like this:

XML:
<skill category="database software">oracle pl-sql package functions and stored procedures</skill>

XSL: (test "database software" for any match in "database sysadm")
<xsl:template match="
exists(
setintersect( tokenize(skill/@category,' '), tokenize('database sysadm',' ')
) )
">

  exists(setintersect(
    tokenize(skill/@category, ' '),
    tokenize('database sysadm', ' ')
  ))

  tokenize(skill/@category, ' ') =
  tokenize('database sysadm', ' ')
