Element <material>

[atoboy]

In our Guidelines, ODD and Schema files we changed the TEI element <material> to include as attribute usage:

<elementSpec ident="material"
 module="msdescription" mode="change">
 <classes mode="change">
  <memberOf key="att.global"/>
  <memberOf key="att.global.linking"/>
  <memberOf key="att.global.analytic"/>
  <memberOf key="att.global.facs"/>
  <memberOf key="att.global.change"/>
  <memberOf key="att.canonical"/>
 </classes>
 <attList>
  <attDef ident="usage">
   <desc>describes the usage of the material</desc>
  </attDef>
 </attList>
</elementSpec>

In current TEI Guidelines they have an attribute function with the same meaning: (https://tei-c.org/release/doc/tei-p5-doc/en/html/ref-material.html).

Proposal: 1) use the TEI declaration instead of ours. So <material> without our modifications; 2) change the encoding of our descriptions accordingly.
