Is inifinite precision of dateTime mandatory for all processors?

Dear XML Schema WG members,

I noticed that "dateTime" type allows infinite precision for seconds, as
well as aribitary long year.

For example,

9999999999999999999999999-05-31T13:20:00.00000000000000000000001+09:00

is an acceptable value (both in lexical and value space).

Is it possible to introduce minimum numbers of digits that must be
supported, as the spec did for "decimal" type?
The idea is that minimally conforming processor does not need to support
infinite length of digits.


Computation over dateTime is inevitable for schema processor (for
example, to check minInclusive facet), and infinite precision support is
a costly operation.


regards,
