Check for spurious whitespace, other than that the error message is as
precise as theoretically possible, stating both the exact location (to
the letter) and nature of the problem.

Other than that, having a metadata-providers.xml file with 300+ lines
seems to be indicative of some deeper misunderstandings or usage
anti-patterns.
But that all pales in comparison when you've been loading InCommon
metadata for years without signature checking that all, of course.
