Here is one. Compare two variables: <xsl:variable name="v1" select="some-xpath"/> <xsl:variable name="v2"><xsl:copy-of select="some-xpath"/></xsl:variable> Are "v1" and "v2" the same? I mean: can "v1" and "v2" be used in a program interchangeably? Answers: 1) yes 2) no 3) implementation-dependant . . . . . . . . . . . . . . . . . . . . . . . . The right answer is (2): no. Changing a use of "v1" to "v2", or reverse, might change the result of a stylesheet. I'll post an example later. Or you can provide your version. -- Oleg Paraschenko olpa@ http://xmlhack.ru/ XML news in Russian http://uucode.com/blog/ Generative Programming, XML, TeX, Scheme | ||||||
