Your answer seems to be in 3.3 of the XML-lang spec:

When more than one AttlistDecl is provided for a given element type, the 
contents of all those provided are merged. When more than one definition is 
provided for the same attribute of a given element type, the first 
declaration is binding and later declarations are ignored. For 
interoperability, writers of DTDs may choose to provide at most one 
attribute-list declaration for a given element type, and at most one 
attribute definition for a given attribute name. An XML processor may, at 
user option, issue a warning when more than one attribute-list declar ation 
is provided for a given element type, or more than one attribute definition 
for a given attribute, but this is not an error.
