RE: [xsl] Weird XPath evaluation differences between Saxon and Xalan

---

In XSLT 1.0, xsl:value-of when applied to a set of nodes gives you the value
of the first node, and ignores the others.

In XSLT 2.0, it gives you the values of all the nodes - by default space
separated.

If you run a 2.0 processor but specify version="1.0" you get
backwards-compatible behavior, i.e. the 2.0 processor gives you the same
result as a 1.0 processor.
