syntaxcomplete#Complete() and nested filetypes

I would like to use syntaxcomplete#Complete() in a filetype that
includes a nested filetype. The only way I have found so far is to
define my own completion function that checks whether the current
position is within the nested filetype, then calls OmniSyntaxList() with
the appropriate regular expression. Something along these lines:

if synIDattr(...) =~ '^nestedfiletype'
matches = OmniSyntaxList(['^nestedfiletype\w\+'])
else
matches = OmniSyntaxList(['^mainfiletype\w\+'])
endif

This is simple enough, but (1) it does not benefit from
syntaxcomplete#Complete() caching, and (2) it requires my own function.

Perhaps, there is a more canonical way to achieve what I want?

Ideally, I would like to set omnifunc=syntaxcomplete#Complete(), and
have Vim figure out the filetype to use for the current completion.
I see that there are some global variables to tweak the completion
behaviour (g:omni_syntax_group_include, ...), but I have not found how
to use them for the my purpose.

Thanks,
Life.
