error in description of teiCorpus

The gloss of the teiCorpus element reads

    <teiCorpus> contains the whole of a TEI encoded corpus, 
    comprising a single corpus header and one or more TEI 
    elements, each containing a single text header and a text.

This was a true description in TEI P3 and TEI P4, but at
some point the content model was changed.  What follows
the header is no longer a sequence of ‘TEI’ elements
(and since the vocabulary can be modified, it is also not
necessarily a sequence of elements defined by the TEI,
so not necessarily ‘TEI elements’ in that sense).

The gloss should probably be changed to avoid stating
a falsehood.  Perhaps it would do just to say 

    <teiCorpus> contains the whole of a TEI encoded corpus, 
    comprising a single corpus header and one or more  
    elements representing part of the corpus, some of
    which may be teiCorpus or TEI elements with headers
    of their own.
