>&#13;		The module <TT
CLASS="classname"
>AttributeValueValidation</TT
> provides all functions for validating attribute values. It provides a function for checking if the attribute value meets the lexical constraints of its type and a function for normalizing attribute values. These functions have been moved into an own module, because they are needed when the DTD subset and the document subset are validated and when the document is transformed. The function for checking the attribute value is again an <TT
CLASS="literal"
>XmlFilter</TT
> function.
