Hi Twibbs

I am also using InDesign CS5.5 and have come across a problem in its revised export to epub function. If you leave the 'unique identifier' field blank in the export options, Indesign is supposed to insert a random unique identifier automatically. I have noticed that this is not happening in epubs that I make, and same seems to be happening with you. Your quoted .opf file reads <dc:identifier id="bookid"></dc:identifier>. A unique reference should be inserted before the closing tag. Unfortunately, epubcheck 1.2 is not detecting this as an error, even though this information is required in all epubs!
