Do you mean a generic XML editor, or some custom GUI that is 
capturing your input into a particular vocabulary?

By formatting, do you mean indentation?

Indentation is appropriate when you have element content, but it can 
be a problem when you have mixed content (sibling elements and text).

If I understand what you are asking for, this isn't true ... such 
indentation would be a feature of the editing tool, not a property of 
the document model.

Yes, a simple identity transform with <xsl:output indent="yes"/> does 
an effect job of indentation on the output.  I especially like the 
indentation choices made by Saxon.

I'm quite sure this is not possible.  If you can cite where you read 
about the configuration, perhaps someone on the list will recognize 
what you see.  Perhaps your program is looking for reserved 
attributes in the document model.

I hope this helps.
