The is no such thing as XmlObject in Jackson so I am not sure what you
are referring to.

As per README of the XML repo, Tree Model is not officially supported
and while I am not opposed to changes that can help with
interoperability there is no intent to make it work like a real XML
tree model like DOM. It is what it is.
Jackson XML module is meant to be used for binding XML to/from POJOs,
and so although it does implement streaming API to work with
data-binding, and by virtue of doing this also does allow use of Tree
Model, direct use of Streaming and Tree Models on XML is not a
supported use case.
