As far as I can tell, the only thing relevant to XS there is `(add-to-list 'auto-mode-alist '("\\.xs\\'" . c-mode))` [download] which is to say they set files ending in ".xs" to C mode. But XS files aren't C code. A snippet for example: `# ----------------------------------------- MODULE = Mozilla::DOM PACKAGE = Mozilla::DOM::NSEvent PREFIX = m +oz_dom_ PRBool moz_dom_DispatchEvent (target, event) nsIDOMEventTarget target; nsIDOMEvent event; PREINIT: PRBool rv; CODE: target->DispatchEvent(event, &rv); RETVAL = rv; OUTPUT: RETVAL` [download] Though at a glance it looks like the syntax highlighting is okay in C mode. It would be neat if there was an XS mode, similar to mmm-mode in that it could use different modes in different regions of the page (e.g. in mmm-mode, the HTML is done differently than the %perl sections; the XS mode could distinguish the C code at the top from the XS code at the bottom).
