Thanks again Macropod.

Wow, I had no idea you could look that deep into a Word file by saving as docx, changing the extension to zip, unzipping it, then opening up, say, the styles.xml file with DreamWeaver to look inside.

But it doesn't really help.

Now I'm in InDesign turning my Word file into a book-quality PDF, and the phantom blockquote's margin indents that my Doc inherited from the HTML are gone so I'll have to put them in by hand.

Partly i can do this by changing the left and right indent for my "epub_extendedquote" style, but I'll have to visit each spot to have it skip a line at the top and bottom of the multi-paragraph extended quotes.
