There is no XSLT 1.1 specification, only a requirements document.

Because there is no suitable cross-language definition of data types that it
can refer to. SQL has exactly the same problem. If you make a call on
my:proc(3.2)
and proc is written in Java then the spec needs to say
- where to look for a function called proc
- what to do if it finds more than one
- how to convert the argument 3.2 into the Java data type expected by the
selected method (e.g. what if it expects a BigDecimal?)
- how to convert the result of the selected method back to an XPath value.
All these things are necessarily Java-specific.
There are of course some things one can say that are not language-specific,
and no doubt the spec, when it emerges, will try to achieve as much
generality as possible.
