Customise the teiCorpus element

[cmil]

The revised DraCor schema should add teiCorpus as a possible start element to the schemaSpec of the ODD and adjust the content model to the DraCor use in corpus.xml files.

I added it as start element. Is an easy fix:

<schemaSpec ident="dracor-api" docLang="en" prefix="tei_" xml:lang="en" start="TEI teiCorpus">

The problem with the corpus.xml is that it is not valid against TEI all. See #44

Just to note that you don't need to use <teiCorpus> : you can simply nest all your <TEI> elements within another <TEI>
