Yes, that is expected behaviour, due to the pretty printer.  In order to
avoid adding extra whitespace around text (which could be significant),
yet still preserve the hierarchical structure of the tree (by
indentation), all "structuring" whitespace is placed inside the tags
themselves.

I agree it is not ideal behaviour.  I would like to offer the
possibility of more traditional indentation as well (as an option).
No-one has yet coded it however.
