externalState is not defined in the second file. But the checker and the
editor should still be aware of it.
Possible?

I tried this solution and it works fine
however, in my language, I'd like not to specify the complete resource
URI, for instance, if no path is specified then the current directory (I
mean the same directory of the file being edited) should be used... is
it possible to do this somehow?
Moreover, I noticed that while the completion for symbols (i.e., ID)
defined in another file works perfectly, jumping to the definition of
that symbol with F3 (or Ctrl+click) does not work...

Yes, it's possible but it's not as simple.
You can either implement your own linking mechanism, by overwriting the
extensions
allElements()
and
allVisibleElements()
or use the hooks provided by EMF (e.g. register a URIConverter with the
ResourceSet).
Hope that helps,
Sven
regarding F3 : Usually it works. So maybe you want to double check your
setup and if it still doesn't work, file a bug report.

Actually I was thinking about a much simpler and faster solution which,
by the way, should also be re-usable: it would only be necessary to
prepend to the string (the name of the file) the same prefix of the
current resource.
This should be easy but again I don't know how to do that: would it be
possible to do this while parsing?
I think this would actually be a useful feature not only for me; the
linking mechanisms are good for "import" (in a Java-like sense), while
I'd need something similar to "include" (in the C-like sense), which, as
I said, would be a quite common feature. Furthermore, I saw that there's
no lexical URI rule: it is implemented through a STRING rule after some
post-processing. The same could be done by providing a psuedo LOCALFILE
rule for instance.
Any help would be appreciated :-)
thanks in advance

P.S. concerning the fact that F3 or Ctrl+click did not work was due to
the fact that I was using
"/myprojectpath/src/includedfile"
instead of
"platform:resource/myprojectpath/src/includedfile"
but again I think there's an inconsistency here: the first form does not
generate an error while parsing (the included file is found) but no text
hover functionalities works...
