Trying to compile

<Variable Name="Test1" bal:Overridable="yes" />

crashes candle. As this code was modified as part of a larger change (switching to XDocument), all extensions modified in the pull request should be looked at.

This is still an issue on v4.0.0.5918 but it is working in version 3.x

@janilemy that's good. The issue is still open against v4.0 which means it hasn't been fixed yet.
