of the native library as possible, without using fragile hacks like custom element
names that break between releases. The downside of this is that we cannot represent
all possible trees; specifically the following are known to cause problems:
Text or comments as siblings of the root element
Docypes with no name
When any of these things occur, we emit a DataLossWarning
