Actually declared variables are part of XPath context. As we haven't
said anything about XPath context i ITS 1.0 no variables were declared.
So I think that ITS 1.0 is in this aspect fine (although it contains
another small problems related to XPath integration).

I think that we should say:

- implementation MUST support its:param
- implementation SHOULD provide means for changing its:param and such
means are implementation defined
