[xml] schema: useful error infoemation?

[Stefan Weigert <Stefan Weigert mailbox tu-dresden de>]

hello again ;)

first: thanks a lot for your tip to look into the test-files. the validation is
working now :)

second: the problem is that i want to have an output like - error in that line
at this column. do you know what i mean? but at the moment i get only a number
- 1866 - in my case.

is there a way to get useful - in means of debugging - output?
