Lastly we figured out why some of the Emblem Schema documents did not validate against the Emblem Schema. Unexpectedly some of the oldest documents did provide a transcription of an emblem's subscriptio as structured markup of lines and line groups. The version of the TEI vocabulary used by the then current version of the Emblem Schema did not allow line group elements (tei:lg) as children of a paragraph (tei:p). We find it interesting to note that apparently no one ever validated the documents against the Emblem Schema or found the validation error worth reporting.

We solved this problem by updating Emblem Schema to use a newer version of the TEI vocabulary that allows tei:lg as child of a tei:p.
