Post Schema Validation Infoset. A goal of Schema was to leave the infoset
unchanged after doing schema processing, unlike DTDs. So, there needed to be
a place to stick all the aditional information a Schema provides an
instance, hence the creation of the PSVI. A processor or application that
doesn't care about the PSVI can still validate a document against a schema
and not have to worry about it.
