Hi Kristian,
PSVI (Post Schema Validation Infoset) is the outcome of schema assessment
of an instance document (or part of it). It includes information like
whether an element/attribute is valid, which declaration/type was used to
validate such element/attribute, the normalized value of an
element/attribute, etc. [schema information] (XSModel) is one property of
PSVI, which models "the schema" that's used for the assessment. So XSModel
is not PSVI, instead it's a part of PSVI.
Interfaces in org.apache.xerces.xni.psvi package are used to return PSVI
properties.

Hi
sorry for intervening in this thread but I got a question concerning the
PSVI you mentioned.

Is the PSVI of a Xerces parsed document an XSModel object or what
actually is the PSVI in Xerces?
I know that when I preparse a schema document I will get a SchemaGrammar
object.
With this grammar object I could know create a XSModel object, so I
would get the PSVI *without* any XML instance parsing !?
I'm a bit confused about that, so please give me enlightenment. :)
Thanks
Kristian
