you can actually look up the format of the md2 model on a number of websites - I think there were also some other limitations which may even have been 256 frames of animation??
Also - I haven't tried with other tools but I found that with milkshape3d when attempting to make a sliding door in the md2 model format it "didn't like" it upon exporting - strange issues with mesh distortion although that could be just milkshape's exporter - it works fine for character models though.
