I added dependsOn CDATA #IMPLIED to the DTD, although I find it strange
that this has always worked, and the dependsOn wasn't in the DTD before :s

However, when I try to go to the basic configuration page again after
adding the dependsOn to the DTD and restarting tomcat, I still get an error.

I think it's the same error as before, but now it no longer mentions the
dependsOn attribute.
