Trying these schemas, I got more errors than -00.xsd. I did not looked in those 
errors.

The schema http://www.oasis-open.org/committees/ebxml-msg/schema/xml_lang.xsd is 
incorrect as per XMLSchema spec. It defines an attribute 'form' on a global 
element 'attribute' which is not permissible.

see: http://www.w3.org/TR/xmlschema-1/#declare-attribute

The datatype of TimeToLive is defined as dateTime in the schema. Thus a value 
'22:20' would give error.

see: http://www.w3.org/TR/xmlschema-2/#dateTime

For the element SequenceNumber, the schema defines a default attribute by name 
'type' and value 'Continue'. But, it does not defines any attribute by the name 
'status'. I have not much idea about ebXML. Thus, either the instance file or 
the schema may be corrected. Someone should correct me here.

The datatype of SequenceNumber is defined as positiveInteger in the schema, 
which has a range greater than or equal to 1.

see: http://www.w3.org/TR/xmlschema-2/#positiveInteger


Hope this helps.

Cheers,
Rahul.
