canonical representation

[Xiaofan Zhou]

Hi, All, I have a question regarding canonical representation handling in xerces-c, specifically, if I define an element of simple type integer in a schema, according to the schema data type specification,  the canonical representation for integer is defined by prohibiting certain options from the Lexical representation (§3.3.13.1). Specifically, the preceding optional "+" sign is prohibited and leading zeroes are prohibited,  I would expect that if in the instance document, the element value is +1234 or 01234 or +01234, then this would be invalid against the schema definition, it is correct? In short, is canonical representation is enforced when xerces-c does validation? Thanks much. Frank
