Mysterious changing property headers

Phil,

I have to admit I spent a chunk of time yesterday debunking formatting
mysteries with properties and it cut into my time adding properties.  Could
you look at our document and help me understand why a heading for a
property is sometimes shown in a large blue letters and other times in
smaller black?  I noticed that our earlier published DUV draft in June
exhibited the same problems.

Any insights would be greatly appreciated.

Thanks,

Eric S
