You have to define what to do with text elements containing only
space (e.g. <element> </element>). By default it should keep the
spaces (Note: spaces include tabs and line breaks).

Further complications: CDATA.

The current fpc xml writer creates the indentation, but messes up text
element.
The laz2_xml writer has a flag to keep the indentation and
preserving text elements. This could be extended with a further flag to
indent elements gaps while preserving text elements.

Or you can simply write a function that works for your xml files.
