<teiHeader> is the header of the document, where we include data that, in a paper edition, would appear on the covers and the credits page, as well as in introductions or prefaces.
It has four main sections:
<fileDesc>: description of the file we are publishing.
<encodingDesc>: description of the codification of the file.
<profileDesc>: description of the profile of the edited file.
<revisionDesc>: description of the revisions history.
Each of these sections is outlined in its own article.
