Does the description, extend and medium relate to the TEI/XML document and not the original source?

[MikeJ1971]

If we are talking about the TEI/XML document, then these might be the elements we use.

The edition details could be used as the description, e.g.:

<edition>English translation of the Irish Exchequer receipt roll for 29 and 30 Edward I encoded as TEI/XML</edition>

For the extent, there is an extent element:

         <extent>11 membranes of source material translated and encoded</extent>
         <!-- <extent>xxxs bytes</extent> -->

If we are talking about the TEI document, then the size and medium could be computationally derived when the file is processed.

However, if we are talking about the original manuscript then we need to look at mDesc element

            <msDesc>
               <msIdentifier>
                  <settlement>London</settlement>
                  <repository>The National Archives</repository>
                  <!-- Is the idno sufficient for the unique reference code for the database? https://github.com/ilrt/Beyond2022TeiTemplate/issues/17-->
