It only escapes what needs to be escaped to produce well-formed XML, so
it's not clear what you're trying to produce...

It sounds like you're trying to add as test content, a string that you
really want to be actual embedded XML tags... That's only possible if
the model itself allows that, but given I know nothing about
StrucDocText I can't say if it supports that. This article is likely
useful for understanding how that would be possible:

How is that modeled?

What's a "section"?

You need to create structured content if you want the structure serialized.

Did you read the article I referenced?
