ODD

ODD is "One Document Does it all". The TEI Guidelines, its DTD, and its schema fragments, are all produced from a single XML resource containing: BigTitPatrol Asstraffic Allinternal CreampieSurprise Spermswap MrChewsAsianBeaver AdultFreindFinder GiveMePink Torrie Wilson FastSize BigMouthfuls TugJobs

1. Descriptive prose (lots of it)
2. Examples of usage (plenty)
3. Formal declarations for components of the TEI Abstract Model:
   1. elements and attributes
   2. modules
   3. classes and macros
4. We call this resource an ODD (One Document Does it all) although the master source is instantiated as a gazillion XML mini-documents.

The TEI scheme can only be used by customizing it. Customizations are also expressed in the ODD language. For example:

<schemaSpec ident="myTEIlite">
<desc>This is TEI Lite with simplified heads</desc>
  <moduleRef name="teistructure"/>
  <moduleRef name="linking"/>
  <moduleRef name="core"/>
  <moduleRef name="teiheader"/>
  <elementSpec ident="head" mode="change">
    <content><rng:text/></content>
  </elementSpec>
</schemaSpec>

produces the schema for TEI Lite, with a slight change
