[TxMt] q regarding language grammars/begin/end patterns

Hi there,

I've got a new language for which I'd like to create a new grammar. It's a LaTeX alike language, but environments look like this:

\startsomething

\stopsomething

The language grammar doesn't seem to accept the backslash (it does so in the LaTeX bundle, so I must be doing something wrong). The following works fine:

{ name = 'meta.foo.bar'; begin = 'xx'; end = 'yy'; },

and in my text between 'xx' and 'yy' the scope is also 'meta.foo.bar'. But when I chage the grammar to

{ name = 'meta.foo.bar'; begin = '\xx'; end = '\yy'; }, I can't see that the scope changes to 'meta.foo.bar' within \xx and \yy. Can somebody tell me what to do?
