I don't know if Altova has a processor of their own, or if they use MSXML or Xalan or whatever. The node-set() function is an indispensable add-on for XSLT 1.0, because it is needed to convert the not very useful so-called "result tree fragments" (or RTF) to full-fledged useful node-sets, on which you can use the axes, which you can't on an RTF, which only allows xsl:value-of and xsl:copy-of. There is msxsl:node-set() for MSXML, xalan:nodeset() for Xalan, exsl:node-set() for processor supporting EXSLT. You need to map the prefix to the correct URI in any case. Should be solvable by doing a web search.
