Well, just for the record, i solve my problem, by using

<xsl:variable name="snode" select="(//Menu)[position()=$pos]"/>

instead of

<xsl:variable name="snode" select="(//Menu)[$pos]"/>

A million neurones i burn to reach this solution!!!

Not just because I guess it to be less bug-prone, but also because I think it's more intuitively obvious, I have started using


as an alternative to the above.

A lot of XSLT code ends up getting thrown at newcomers to maintain these days. Part of my job is to make my code as clear as I can to people starting with the language. It's a design, er, "wrinkle" that //node[$pos] doesn't return what people guess it should (expect in buggy systems), before they learn the gory details of the XPath productions -- and that includes implementers. (I know this isn't the bug you found, but it's nearby isn't it?)
