XML validation problem in apache when upgrading SP from v2 to v3

[Cantor, Scott]

> The initial few lines of the shibboleth2.xml file with the XML declarations are:

That's a 2.0 configuration namespace, so that has to be consistent throughout the file. If it's bumped to 3.0 then there are certain old settings that break but either way it's got to be consistent across the file.

Per the docs, run in 2.0 mode, check for warnings, fix them, then bump the namespace.
