[Openal] OpenAL and EAX (EFX)

I'm trying to implement occlusions, obstructions and exclusions in my
project. I am simply using the methods used in the EFXFilterWin32
(AL_FILTER_LOWPASS etc) to add various filters to the sounds. But I don't
understand the need for such structures as EAXOCCLUSIONPROPERTIES that are
defined in the EFX-UTIL library as it seems to be that I can get these
effects (occlusion etc) to work without the need of these structures.
Can I do occlusions, obstructions and exclusions with some modification of
the EFXFilterWin32 code or do I need to use ConvertOcclusionParameters and
EAXOCCLUSIONPROPERTIES etc to achieve this?
