Exposing actual values in PSVI

PSVI currently only expose normalized values for elements and attributes. 
It'd be really useful if it also exposes the actual values (values from 
simple type value spaces) if they are validated by simple types. This will 
greatly help data binding of PSVI.

Note that we already expose actual values for value constraints, where the 
{value constraint} property of element and attribute declarations consists 
a "value" portion which is an actual value.
