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)
