Answer 1

This is a bug:

• Bug #48527: DOM XML classes do not expose properties to Reflection

For some reason, DOM* classes do not expose their properties, neither to Reflection, nor to any other function capable of inspecting objects. You'd have to write a custom inspector that collects the properties manually.
