I was looking at an epub converted by Calibre.
Cleaning it up I ran epubcheck and found it warning on numerous lines:

ERROR(RSC-005): Error while parsing file 'element "div" not allowed here; expected the element end-tag, text or element "a", "abbr", "acronym", "applet", "b", "bdo", "big", "br", "cite", "code", "del", "dfn", "em", "i", "iframe", "img", "ins", "kbd", "map", "noscript", "ns:svg", "object", "q", "samp", "script", "small", "span", "strong", "sub", "sup", "tt" or "var" (with xmlns:ns="http://www.w3.org/2000/svg")

That's the "<div class="calibre11">" line below.
Obviously this is awful spaghetti code, but I thought it was at least valid.
Code:
<div class="calibre14">
<span class="calibre15">
<div class="calibre11">
<span class="calibre9">ABC<br class="calibre11"/> </span>
</div>
DEF
</span>
</div>
Is it invalid to have a div within a span? Sigil's "well formed"check is OK, all readers are OK.
