Re: regexs, grouping (?) and XSLT2?

  	<dateIssued encoding="w3cdtf">1967-08-22</dateIssued>.

   Is it, then, technically right or wrong to have the following?

	<dateIssued encoding="w3cdtf">1967</dateIssued>


It's schema valid as, as you say, the schema doesn't constrain the value
at all (It can't due to limitations in W3C schema, in Relax NG you could
constrain the element content based upon an attribute value, but W3C
Schema can't do this)

W3C Schema have several (to put it politely) date related types and each
of those values is valid in at least one of them, so it depends on the
definition of  encoding="w3cdtf" in MODS, whether they mean by that
"Any date or time related type defined by W3C"
or
"A specific date related type defined by W3C"

1 minutes worth of looking at the schema and google suggests it isn't
defined at all in the easily accessible public pages about MODS...
