We (the W3C XSL WG) should have updated the requirements document to change
"1.1" to "1.0". The XSL Working Group is not committed to retaining XSLT 1.1
syntax in XSLT 2.0 in a compatible form. In fact this applies to any working
draft, it would have been true even if XSLT 1.1 had been progressed.

However, we are treating all the functionality of XSLT 1.1 as being on the
requirements list for XSLT 2.0, with one notable exception: the
standardization of Java and JavaScript language bindings. The WG has made a
decision that is best kept out of the core XSLT specification: some members
were hoping that the Java bindings might be picked up in a future JAXP
specification instead.

The qualification (if you change 1.1 to 1.0) means that the compatibility
requirement only applies to stylesheets that contained no errors as far as
the XSLT 1.0 specification is concerned. If a stylesheet produced an error
in 1.0, it's not guaranteed to produce the same error in 2.0. (For example,
select="$rtf//item" might start working...). This has nothing to do with
implementations - the spec determines whether a stylesheet is in error, not
an implementation.
