Do you think that it is possible to create a Lightweight markup language [1] editor with Xtext?

I know a lot of this language have difficulties to define a proper grammar, but in my opinion it could also be a language inspired by these markup languages and not exactly one of them.

Do you know if something like this already exists?

Could the work done by Alex Lagarde (EMF Model of structured text [2]) be useful?

The lightweight markup languages typically depend heavily on lexing,
significant whitespace, and position of tokens (both individually and as
token pairs; i.e. there is one meaning if they are on same line, in an
unbroken sequence of text, or similar contextual rules).

The fit is far from ideal for Xtext.

I integrated support for Rdoc/markdown inside comments in cloudsmith /
geppetto @ github. I did not implement the text parser using Xtext, but
I integrated formatting into the overall Xtext process of doing formatting.

Have you looked Mylyn text?

(I would love to have something like Mou (Mac application) in Eclipse
instead of as a separate application - it is a markdown editor).

You may want to have a look at Xdoc

@Lorenzo Bettini:
Thanks for the pointer on XDoc, I will try to have a look into it.
Where can I see text examples (that are valid XDoc snippet) to figure out the syntax?

@Henrik Lindberg:
Thanks for your explanations...

If I reverse the problem:
Given the "EMF Model of structured text" (which is the EMF version of the internal model used by Mylyn Docs WikiText), what kind of text representation can I obtain with the XText technologies?

I was thinking of:

{h2: Hello World}
This some {strong: structured} text.

PS: after having a look at the markup.ecore model, I think my example is still to far from the proposed model.

here are some files
http://git.eclipse.org/c/emf-parsley/org.eclipse.emf-parsley.git/tree/doc/org.eclipse.emf.parsley.doc/xdoc

or you may want to have a look at the xdoc files in the xtext sources:
Xtext help is written in Xdoc.

cheers
Lorenzo
