deferred parsing does not watch SSI changes?

Hi,

I have just got the Deferred Parsing of XMLC 2.2+ working and I am
amazed by that. But I have noticed that the XMLC deferred parser does
not notice when the SSI file is changed. I have to change all the HTML
files that include the SSI (add a white char or remove it) in order to
get the changes compiled. This is annoying. How can this be fixed,
please?
