General Comparison in 1.0 compatibliity mode: cannot compare xs:string with xs:integer
100%
Description
W3C test case boolean-069 fails saying "cannot compare xs:string with xs:integer".
We do not appear to have the logic in place to handle string-to-number comparison according to the 1.0 compatibility rules.

There seems to be some confusion as to whether we support 1.0 compatibility mode. In the documentation we say that we don't; but in that case we ought to reject stylesheets specifying version="1.0" (as Saxon-HE 9.8 now does). Any many aspects of 1.0 compatibility mode are in fact implemented. We need to decide one way or the other. There are good reasons for supporting it if we can, because we want to make transition easy for stylesheets written to run using native browser implementations of XSLT 1.0.

I have modified the "gc10" implementation so string-to-number conversion in 1.0-mode general comparisons is now working (and this test case passes).
Generally I think it is the case that we DO implement 1.0 backwards compatibility. A lot of the work (casting in the function conversion rules, extracting the first value of a sequence) is actually done at compile time - the SEF file contains the code to do the necessary casting. In the case of general comparisons, we had implemented some of the BC rules but not all. For arithmetic (arith10) we have code in place to implement BC semantics. There are a few other cases where BC comes into play, e.g. in xsl:number, but we should handle these on a case by case basis.
The documentation should say that 1.0 backwards compatibility IS supported.
