[xsl] Re: document() merge DISTINCT -- a Simple Functional Solution

---

---

Two remarks about this solution:

 1. The following four lines obviously were not taken care of and may be safely
removed:

      <xsl:variable name="vList" select="$arg1/@id"/>
      <xsl:variable name="vList2" select="$arg1/*/@id"/>
      <xsl:variable name="vElem" select="$arg2/@id"/>


 2. Not only in this particular case, but always when using the union of several xml
documents, there's no guarantee about the order of the elements -- therefore the
result of the given example may be different depending on the particular XSLT
processor used. In case the order is important, then the different xml files have to
be unified one at a time, using RTFs and the xx:node-set() extension function.

Cheers,
Dimitre Novatchev.
