SyntaxDescriptor is useless, knowing the macro won't give you the
syntax in many cases since you need the current syntax in a given
context. But yes for very standard macros this could be found in the
context and previous metadata blocks (provided the user did not
removed a metadata block by mistake, I guess the WYSIWYG could have
some protection against that).
My point was more about future custom inline editors we talked about
for which it would be much easier if they can explicitly give the
information if there is a transformation need.

Anyway, I though about it a bit more and I think we don't need to
introduce anything in the macro annotation: the same metadata the
WYSIWYG is using to know that a content is editable could be used by
the HTML parser to know it should convert it instead of getting it
from the annotation. And this metadata is planned to support
parameters too. It also cover future custom editors need since there
is a metadata for the syntax.
