Thanks Jellby and Donna for your help.
I am down to one set of errors:
I am using internal links for an internal TOC with
<p class="left"><a href="#foreword">Foreword</a></p>
The ERROR reference below is to the line (line 119) with the <a id="foreword"></a>. It references this each occurrence through the document with different IDs i.e., <a id="c1"></a> or <a id="c2"></a>
ERROR: miller_cross_purposes.epub/Cross_Purposes_NOOK_final_32011.html (line 119): element "a" from namespace "http://www.w3.org/1999/xhtml" not allowed in this context
These ERROR messages are generated by epubchecker.
FlightCrew is only unhappy with one line in the HTML file:
element 'a' is not allowed for content model '(p|h1|h2|h3|h4|h5|h6|div|ul|ol|dl|pre|hr|blockquo te|address|fieldset|table|switch|form|noscript|ins |del|script)'
This is assigned to the next to last line of the HTML file which reads:
I read somewhere that FlightCrew was better at this stuff than epubchecker. The first being in English and the latter one in Codelish. While I can read the English, I am still stumped by what it means.
What to do?
