It is currently impossible for macros which have a body that contains wiki markup to be correctly rendered or converted when switching between RichText and wiki markup editing. For example, the {toc-zone} macro generates a table of contents for all headings contained within it's body. However, when it's contents are viewed in the RTE bad stuff happens. Here are the options, with all possible combinations of the 'supressMacroRenderingDuringyWysiwyg' ('Macro Rendering') and 'suppressSurroundingTagDuringWysiwygRendering' ('Surrounding Tag') methods:

Essentially, it seems that the 'Suppress Macro Rendering' option is not working as expected - it seems that 'Suppress Surrounding Tag' is the only flag which has any effect, and when enabled it will do both - either display the markup for everything or display the markup for nothing.

In any case, I think that a better option would be to allow an option for macros to specify that the macro body to be rendered, rather than the whole macro. Some cases will still want the exiting options (if they actually worked, that is), but in the example of {toc-zone} it would be much more useful to be able to display the

macro itself, but have it's body markup rendered as per usual. As such, perhaps an extra option to 'suppressMacroBodyRenderingInWysywiyg' could be added, which will be trumped if the 'suppressMacroRenderingInWysiwiy' returns true.

But even if that is not added, getting the other two flags to work correctly would help a lot...
