I dont know if this is what youre looking for:
http://openexr.com/TechnicalIntroduction.pdf
But openexr.com is probably the best place to look for tech specs.

At least in case of my image it contains multiple layers(for example direct_diffuse and direct_specular) and these layers contain each their own r/g/b channels. Layers are a way in exr format to group channels. My technical knowledge doesnt go deeper than that with exr format.

As far as I can tell, EXR does not contain layers, but does have "parts", which appears to be similar.

The IM developers will have to respond regarding interest and availability to modify the EXR reader.
