This is a comment on

XML Schema Part 2: Datatypes
W3C Recommendation 02 May 2001
Appendix A

http://www.w3.org/TR/xmlschema-2/#schema

I have not found equivalent comments in:
http://www.w3.org/2001/05/xmlschema-errata

The datatypes for recurring calendar events (specifically gMonthDay, gDay 
and gMonth) are all recorded in appendix A with:


         <hfp:hasProperty name="cardinality"
                 value="countably infinite"/>


However it appears that there are at most 366 days in a year, and at most 
59? timezones or maybe 290000 if we take an extremist view of the possible 
timezones. (Alternatively, the lexical form is of finite length and comes 
from a finite vocabulary, hence there are finitely many different lexical 
forms).

Is this an oversight?
