Hi.. According to spec. Two non-group particles overlap if They are both element declaration particles one of whose <http://www.w3.org/TR/xmlschema-1/#e-name> {name} and <http://www.w3.org/TR/xmlschema-1/#e-target_namespace> {target namespace} are the same as those of an element declaration in the other's <http://www.w3.org/TR/xmlschema-1/#key-eq> .substitution group.. In the following schema, element ref = b and element ref = c are both element declarations and c's name and target namespace are same as b's substitution group's name and targetnamespace. So, they both overlap. and both are under <choice> model group. So, the content model is non-deterministic. <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="a" type="xs:short" substitutionGroup="b"/> <xs:element name="b" type="xs:decimal" substitutionGroup="c"/> <xs:element name="c" type="xs:decimal" block="substitution" substitutionGroup="d"/> <xs:element name="d" block="substitution"/> <xs:element name="foo"/> <xs:complexType name="base"> <xs:choice> <xs:element ref="b"/> <xs:element ref="c"/> <xs:element ref="d"/> <xs:element ref="foo"/> </xs:choice> </xs:complexType> <xs:element name="doc" type="base"/> </xs:schema> But one of the XML parsers is not giving any error about the non-deterministic content model. Please reply me whether the elements <xs:element ref="b"/> and <xs:element ref="c"/> will overlap or not. and whether the content model is non-deterministic or not. Thanks and Regards, Bharath.
