http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6275 Validation fails with 'Unknown content spec type' if a type is extended using xs:all [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |INVALID ------- Additional Comments From [EMAIL PROTECTED] 2002-02-07 17:52 ------- Consider "Schema Component Constraint: All Group Limited" from http://www.w3.org/TR/xmlschema-1/#coss-modelGroup, which states: When a model group has {compositor} all all of the following must be true: 1 one of the following must be true: 1.1 It appears as the model group of a model group definition. 1.2 It appears in a particle with {min occurs}={max occurs}=1, and that particle must be part of a pair which constitutes the {content type} of a complex type definition. 2 The {max occurs} of all the particles in the {particles} of the group must be 0 or 1. Since the resulting content model of the extension is a sequence of (base content type (e.g. sequence), derived content model (all))->does not meet 1.1 (because they're not in model group definition) and they aren't the content type of a complex type definition, because they're part of a sequence. Also, according to the schema spec (http://www.w3.org/TR/xmlschema-1/#cos-particle-extend) you cannot extend an 'all' content model unless you are only adding attributes.
