LWO LightWave Object file format problem

I'm trying to extract mesh data from Lightwave object(LWO) files. I've found a couple documents describing the format but downloaded some models that seem contradictory to the specs.

The format seems fairly simple and I have some files loading perfectly.

In some others there are problems with the "POLS" chunks. According to the specs at http://www.sandbox.de/osg/lightwave.htm , a POLS chunk is of the form "POLS { ( numvert[U2], vert[U2] # numvert, surf[I2] )* }" but I've used a hex editor to view some files that show "FACE" chunks starting at the beginning of a POLS chunk.

Do you know how to handle this problem or where to find a more updated, accurate description of the format?
