Only the effective (first) declaration for an attribute is reported. <p> The reader passes the name of the associated element in <em>eName</em> and the name of the attribute in <em>aName</em>. It passes a string that represents the attribute type in <em>type</em> and a string that represents the attribute default in <em>valueDefault</em>. This string is one of "#IMPLIED", "#REQUIRED", "#FIXED" or <a href="qstring.html#QString-null">QString::null</a> (if none of the others applies). The reader passes the attribute's default value in <em>value</em>. If no default value is specified in the XML file, <em>value</em> is QString::null. <p> If this function returns FALSE the reader stops parsing and reports an error.
