I am familiar with TEI lite.
When the standard is converted to a Schema, I strongly
recommend that you provide a very detailed tag library.
Schemas are very difficult to read and interpret. A good
model for documentation would be the EAD tag library at
Each tag is defined, and possible parent and child tags
for the given tag are listed. Examples are also provided.
The EAD Tag Library also has a good explanation of
linking tags and attributes.
The DTD for P4 was relatively easy to search and
The Schema and DTD for P5 are much more difficult.
I also would suggest that you provide detailed
information about what schema validators will work,
provide detailed information on how to install and
configure them and provide information on where they
can be obtained.
