Item13496: WysiwygPlugin unable to handle paramaterized PUBURL / SCRIPTURL macros

Need some enhancement post 2.0

IMG tags that use parameterized versions of PUBURL or SCRIPTURL don't render correctly during edit. And the round-trip code doesn't know about the new parameterized format.

Also somewhat related, IMG tag with any macro not supported for the roundtrip ends up as a corrupted image during edit due to the unexpanded macros.

See Item13495 for reference to examples

The reason is that %PUBURL{param="val"}% is not statically reversible when used in the context of a URL. The only way I can think of to handle it is to use an XML data param to store the original URL param, then blindly expand the URL. For example,

<img src="%PUBURL{web="Toast" topic="AndButter"}%">

modify in TML2HTML to

<img src="url expansion of macro" data-unexpanded-src="%PUBURL{web="Toast" topic="AndButter"}%"/>

Then, in HTML2TML compare the post-edit src with the expansion of data-unexpanded-src and if they differ, assume that src is a new value.

As you can see, this is quite a lot of work. Too much for 2.0 So my view is that we document the limitations of PUBURL (and friends) in a Support FAQ.
