ISSUE-74: XSD URIs for facets

ACCEPTED: Use the xsd namespace for the facet names

This item has been at the end of the agenda but not reached on several
telecons. In the interest of discussion that moves toward resolution of
the issue I'll re-iterate what I took as the pros and cons previously

+ The semantics of the facets are defined by reference to the XSD
specification and re-use of the XSD URIs is possible (see URI minting
text at [1])

- Non-XSD datatypes may be standardized (e.g, [ISSUE-87]) and it is not
clear that application of XSD facets to such datatypes is consistent
with XML Schema WG's intentions

- If additional, non-xsd, facets were standardized at some point in the
future, they would likely use URIs that are not XSD URIs, and such
heterogeneity in facet URIs is undesirable (at least by some)

Please reply if there were additional pros / cons I missed.
