I think that is reasonable, so long as the metadata is simply ignored. 
What I would like to avoid is any situation in which the UA strips the 

Generally, I think we need to strongly word the well-formed XML 
requirement in terms of tool conformance, and only require of the UA 
that it either ignores the metadata completely or makes it visible to 
user in some way if desired. If the metadata is malformed and can't be 
parsed to display to the user, then it is ignored, with an error message 
at the UA's discretion.
