<!-- typical usage:

-->
<!--
Read a corpus of TEI P5 documents and construct
an ODD customization file which expresses the subset
of the TEI you need to validate that corpus
-->
<!-- How does this work?
1) start a variable and copy in all of the TEI
2) read the corpus and get a list of all the elements and their
attributes that it uses, put that in the same variable
3) process the variable and read the TEI section. if an element or
attribute is not present in the corpus section, put out a delete
customization;
if the attributes of an attribute class are never used
that class may be deleted only if it doesn't claim membership in any other class
or, if it does, none of the attributes from that other class is used too
4) for every attribute which is of type "enumerated", construct a
valList
