[XML Schema 1.1] Is vc:type(Un)Available and vc:facet(Un)Available redundant?

Hi Folks,

If I specify vc:minVersion and vc:maxVersion doesn't that dictate what types and facets are available?

For example, if I specify vc:minVersion="1.1" and vc:maxVersion="1.1" doesn't that mean vc:typeAvailable="xs:precisionDecimal" and vc:facetAvailable="xs:assert" are true?

It occurs to me that vc:type(Un)Available and vc:facet(Un)Available are never needed; my desires can always be specified just by using vc:minVersion and vc:maxVersion. Do you agree?
