questionable wording in 1.5 Non Normative References, part 1

The current text in 1.5 Non Normative References in part 1 is:

The individual parts of the OpenDocument specification may contains further non normative references.

 

I stumble about "may contains".

 

I could image something like:

The individual parts of the OpenDocument specification each lists its own set of non normative references.

 

or

 

The individual parts of the OpenDocument specification contain further non normative references.

 

It is editorial, but because I'm not sure about a correct wording I have put it into an issue instead of our type list.
