/**
* Word (2007) can't open a docx if it has more than one
* comment with the same ID. Similarly for footnoteReference
* and endnoteReference.
*
* Bookmarks: duplicate, missing (or half missing) bookmarks
* don't seem to trouble Word, so we don't check for these.
*
* Since docx4j 3.0, two content control integrity checks are
* also done here:
*
* 1. w:tr/w:sdt must contain w:tc, and w:tc must be non-empty
*
* 2. w:tc/w:sdt must be non-empty
*
* Note that the w:sdts can be nested, so simple parent/child
* checks aren't sufficient.
