Actually, dual times (like 3/4 5/4) are not easy to support in lilypond, 
because lilypond relies on the time signature to calculate the measure length 
(the | are just checks, they don't cause a new measures!).

For dual times, each measure length might be either of the two values, 
possibly with no logical structure, so lilypond does not have any information 
about the measure length.

(For dual times like 3/4 6/8 which have the same length the measure length is 
not a problem, but now lilypond doesn't know which automatic beaming to apply 
to a measure...)

Cheers,
Reinhold
