I think the rationale was:
- It uses 800KB
- It makes Tomcat takes about 10 - 15% more time to startup than Crimson
- Few people use it (a significant amount use JDK 1.4, and IBM JDK users 
have it integrated ;-) )
- We're not going to do a JDK 1.4 version of TC
- Server side validation is dead slow (esp schema validation ;-) ), so 
it is not a problem if it doesn't work ;-)
- Better tools are IMO provided for validation (come on, try the 
deployer a little bit :) ); the deployer also uses the validation code 
you put in ContextConfig (so don't worry, your code is not useless even 
if validation is disabled): see the ValidatorTask

You should be able to unearth that in the archives and see what the 
reasons given were.
I think these are decent reasons for removing it from the server package.

Really ?

It doesn't seem a fatal error, though. The webapps are working despite 
the error.
