After some more thinking, it seems to me that it would be in fact 
rather easy.  For the parser, it would be exactly like parsing 
@example/@format/@display...  For the converter it would be quite easy
since the output would simply be the text inside, and the only thing
to take care of would be that text should not be protected.

The same rules for what may appear inside would apply as for 
@example/@format/@display... that is mostly everything except for
@node, @chapter and a few other @-commands.


Also, I think that what would be best would be to have the 2
possibilities, raw html as in tp currently and an other block 
command where @-commands are expanded as you propose.

Maybe we could even use this opportunity to have something more
generic, like @inlineraw, that is without the format name in the
command name.



So, it could be like

@blockraw html
Here HTML characters are not escaped, and @-commands are not expanded.
@end blockraw

@blockfmt html
Here HTML characters are not escaped, but @@-commands are expanded.
@end blockfmt

And to generalize @ifhtml we could even imagine something like
@blockiffmt html
Here HTML characters are escaped and @@-commands are expanded.
It is exactly the same as @@ifhtml/@@end ifhtml
@end blockiffmt



And then there would be the corresponding @inline stuff:

@inlineraw{html, HTML characters are not escaped, and @-commands are not
expanded except for @atchar{} @lbracechar{} and @rbracechar{} (and
@backslashchar{}?)}

@inlinefmt{html, HTML characters are not escaped, but @@-commands 
are expanded }

@inlineiffmt{html, HTML characters are escaped and @@-commands are expanded.
It is similar with @@ifhtml/@@end ifhtml (and you proposed @@inlinefmt as
name for this command)}


Would that be possible and interesting?
