RE: [xacml-comment] XACML 2.0: Small error in dayTimeDuration

[Florian Huonder <fhuonder@herasaf.org>]

Why this restriction?
As I understand the data type is a "subset" of the xs:duration that is a
duration, with the meaning of a time-span.
The xs:duration part of day is specified as "nD the number of days" (from
http://www.w3.org/TR/xmlschema-2/#duration). In my opinion this means that
it can be a number of arbitrary length.

Help me out if I am wrong.

Regards,
Florian

Ok, makes sense. Wouldn't this match -P100D10H3M12S as well?

It is kinda messy but I think this is the more precise match:

[-]?P(1|0){0,1}(\p{Nd} ...

What do you think?

thanks
