Re: [docbook-apps] two date entries in EPUB package.opf file

Hi Peter,
Yes, the dates still are not handled quite correctly.  Currently the 
date can come from <date>, <pubdate>, or copyright/year.  There should 
be a single template that selects one based on a priority,  which I 
presume would be pubdate, date, then copyright/year.  I'll log this as a 
bug.

Currently date and copyright/year are mutually exclusive for the date 
metadata, so if you change your pubdate element to a date element in the 
info, then it will output a single date in the opf.
