[relaxng-user] notAllowed element and trang

[CAUBEL, Hugues]

Hello,

I have a problem of converting "notAllowed" element to xsd with trang. 

With the example:

start = DocumentRoot

DocumentRoot = element document {AdditionalStruct,
				      para+									
}

AdditionalStruct = notAllowed
para = element p {text}

With trang, it will be translated in xsd into:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
  <xs:element name="document" abstract="true"/>
  <xs:element name="p" type="xs:string"/>
</xs:schema>

I don't understand why trang translate "document" element in an abstract element ?
Is it a bug of trang or something I don't understand in "notAllowed" element ?

I have notice that when I used "notAllowed" element as optional element, like

DocumentRoot = element document {AdditionalStruct?,
					 para+									
}

the result xsd is what I expected:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
  <xs:element name="document">
    <xs:complexType>
      <xs:sequence>
        <xs:element maxOccurs="unbounded" ref="p"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="p" type="xs:string"/>
</xs:schema>

What I am missing ?
