The effect is described in XSLT section 2.5.

If you specify version="1.0", then an XSLT 1.0 processor must report an
error if you use an XSLT or XPath construct that is not defined in version
1.0.

If you specify version="2.0", say, then an XSLT 1.0 processor must attempt
fallback processing before reporting an error when you use such a construct.
The intent is that you can write a stylesheet that uses XSLT 2.0 features
but defines fallback processing to be invoked if it is run with an XSLT 1.0
processor.
