The storage format may be called "XML with wiki-formatted textnodes". We keep XML elements for 
general structure, and optionally use wiki syntax for HTML formatting.

As an example, you type:

<element name='foo'>some *bold* text</element>

When loading it with fpdoc, first the xml parser parses this and creates an element with a textnode.
Then it passes content of text node ('some *bold* text') to wiki-or-whatever parser. That parser, in 
turn, recognizes 'bold' and creates another DOM element:

some <b>bold</b> text

This stuff replaces the content of 'element' tag in the original XML.
At this point, if you save the DOM tree, you'll lose all wiki markup and get pure XML.

Of course, you may edit with tags as much as you wish. If the original example already contains 
'bold' tag:

<element name='foo'>some <b>bold</b> text</element>

then the wiki parser will be called 3 times (for 'some ', 'bold' and ' text'), but that will be 
effectively a no-op.
