Using command line:
ebook-convert input.xhtml outout.epub
ebook-convert input.xhtml outout.mobi

I get these Errors:
Prefix epub not found.
Selector: No namespaceURI found for prefix u'epub' [179:10: type]
SelectorList: Invalid Selector: nav[epub|type~="toc"] ol

CSS:
nav[epub\:type~="toc"] ol
{
list-style: none!important;
}

and if I do this:
nav[epub|type~="toc"] ol
{
list-style: none!important;
}

I get this:
SelectorList: Invalid Selector: nav[epub|type~="toc"] ol

so both styles of defining epub fail.

It creates the files, but the nav system was replaced losing most of my links.

Does Calibre support ePub 3 Selectors?

Thanks for any help.
