However, I neglected to notice that all of the html files in the EPUB container were all added as raw files. 
So it’s really just unpacking the EPUB zip into raw/ . 
Serving them up still works, but I’m guessing that will limit some of the search features on the unparsed files.

BTW: I was pleasantly surprised to discover that when I made a BaseX database with an ePub zip file, and 
selected the appropriate options ( Parse files in archives, add other files as raw files ) 
I was able to serve and view the ePub files thru the rest interface, and links from the TOC to other document parts,
as well  as images in the ePUB all worked.
