Description
The KeyInfo schema is open to extension, but the XML processing code in the library is not. It just rejects any child element it doesn't know about, which would be ok, but it also throws an exception and halts processing, which is not.
Minimal fix is to ignore the unknown children.
A better fix is to expose them as a DOM element, but this requires ABI changes, so will wait for 1.5.0.
