Documents marked up using the IMT have minimal headers at the moment. These need to be expanded, with the addition of two different blocks of information:

The <publicationStmt> element needs to be fleshed out like this:

<publicationStmt><idno>arrest_contre_les_chastez.xml</idno>
  <publisher>Humanities Media and Computing Centre</publisher>
  <pubPlace>
    <address>
      <addrLine>University of Victoria</addrLine>
      <addrLine>B.C., Canada</addrLine>
    </address>
  </pubPlace>
  <date value="2004-08-20">20 August 2004</date>
  <availability status="free">
    <p>
Copyright 2004. This text is freely available provided the text is distributed with the header information provided.
    </p>
   </availability>
</publicationStmt>

The second is the sourceDesc, which needs to contain at least one <biblStruct> element, for the original publication, and possibly more, for cases where they have been republished in later anthologies. This is an example:

<biblStruct>
  <monogr>
    <title>Sermon pour la consolation des cocus</title>
    <author><name>anon.<reg>anon.</reg></name></author>
    <imprint>
      <pubPlace>Paris</pubPlace>
      <date value="1624">1624</date>
    </imprint>
  </monogr>
</biblStruct>
<biblStruct>
  <analytic>
    <title>Sermon pour la consolation des cocus</title>
    <author><name>anon.<reg>anon.</reg></name></author>
  </analytic>
  <monogr>
    <title>Le Bibliophile fantaisiste ou choix de pièces désopilantes de rares</title>
    <imprint>
      <publisher>J. Gay et fils</publisher>
      <pubPlace>Turin</pubPlace>
      <date value="1869">1869</date>
      <biblScope type="pp">359-70</biblScope>
    </imprint>
  </monogr>
</biblStruct>

Where dates are vague, we can use the precision attribute to specify certainty, and put a date range in the date tag content:

<date value="1670" precision="low">1650-1680</date>
