So perhaps we're in a situation of saying *if* an UA performs XML 
validation of the WOFF file and finds that either or both the metadata 
or private data is invalid, then...

I agree with Christopher that the preferable result in that case would 
be that the whole WOFF file is considered invalid and should not be 
used. If a font fails to display, that's then a signal that there is 
something wrong with the WOFF file, which can then be fixed, rather than 
a file with invalid data being persistently served.
