Description

With the example below, the validation returns "type ' ItemT' specified in 'xsi:type' cannot be resolved".
Obviously, Xerces does not do Attribute Value Normalization applying whiteSpace="collapse" on the attribute 'xsi:type'.
The value of the attribute 'xsi:type' is QName (see http://www.w3.org/TR/xmlschema-1/#xsi_type). QName is an atomic type (see http://www.w3.org/TR/xmlschema-2/#built-in-datatypes). For atomic datatypes the value of the whiteSpace facet is 'collapse' (see http://www.w3.org/TR/xmlschema-2/#rf-whiteSpace).

The command line used is: DOMCount.exe -v=always -s -f -n Type.xml
