Description Sandy Gao 2005-11-11 02:40:56 UTC
Add a [value] property to the PSVI for attributes and for elements validated 
with simple content. This candidate requirement is facilitated by RQ-144, as we 
make clear that the [value] property need be computed only if needed.

With a [value] property, we can also suggest to Query that they augment the 
famously vague Data Model stipulation that:

"In the general case, dm:typed-value constructs a sequence of atomic values. 
These values are derived from the string-value of the element and its type, in 
such a way as to be consistent with validation."

Instead, or in addition one could put into their PSVI-to-DM mapping:

"string-value (unchanged)

The [schema normalized value] PSVI property if that exists, or the [normalized 
value] property.

typed-value (new)

The [value] PSVI property (reference to new PSVI property)

Comment 1 Sandy Gao 2005-11-11 02:41:58 UTC
In its meeting of 2004-03-12 [1], the Working Group decided (Henry Thompson 
dissenting) to classify this item as Non-goal.

This item was discussed in the meeting of 2004-05-13 [2].

Comment 2 C. M. Sperberg-McQueen 2006-03-15 01:23:16 UTC
The Working Group took this up again and discussed it on the
telcon of 17 February 2006.  There was not consensus that the
proposed {value} property should be added, but there was
a consensus that further discussion in the absence of a
concrete proposal was unlikely to benefit the Working Group.
Accordingly, the Working Group asked the editors to draft 
wording for the proposed addition, so that the Working Group 
could examine a concrete proposal and make its decision 
informed by that examination.
Comment 3 C. M. Sperberg-McQueen 2006-10-09 21:09:59 UTC
On 6 October 2006, the Working Group approved a proposal to add
a [schema actual value] property to attributes and elements.  The
approved wording now appears in the status quo version of the
spec and will be included in the next public working draft.

Accordingly, I'm marking this RESOLVED / FIXED.  Sandy, I believe
you were the originator of this issue; if you were, and if you are
satisfied with the resolution, please close the issue.
