Remove noproof tag and container (if empty)
it seems that
noProof is a wrapper for MS Word instructions and hence can be removed. If the parent contains no content then I think it can also be removed and all other extraneous elements.
"This element specifies that the contents of this run shall not report any errors when the document is scanned for spelling and grammar"
