I remember some of the discussion for aligning these types in the hierarchy
before when I was involved with the WG, but I don't remember the option
presented in my original comment here ("minimal precision") being considered. I
mainly remember a proposal where precision=absent for xs:decimal, but that
expands the value space of xs:precisionDecimal since the latter doesn't allow
precision=absent for numeric values.

What is the extra machinery for treating xs:d as a "minimal precision" xs:pd
(and xs:integer as an integral-presicion xs:pd)? I take it instead of different
lexical mappings, you would have a shared lexical mapping that is conditioned by
a precision-mapping facet, whose values would be exact, minimal, or integral.
Any other machinery or is that already too much?

Anyway, my memory is faulty and probably my analysis, too.

Thanks for the factual corrections on the lexical mapping issues for integer and
token.
