Two EPUB 2 content-model gaps, from one MobileRead post by Doitsu (#140)
and the audit it prompted. Both are findings epubcheck reports and we did
not; nothing here changes EPUB 3 behaviour.

Fixed

  • <blockquote> is block-level in an EPUB 2 document. XHTML 1.1 gives
    it the same Block.model as <body>, so an inline element, a <br/> or
    loose text directly inside one is an RSC-005, and an empty one is
    reported as incomplete. The reported case — an <a>, a <br/>, a
    <span> and bare text inside a <blockquote> — now draws all five of
    the errors epubcheck draws, where it previously drew none.

    <noscript> has the same model and had the same gap. Those two and
    <body> are the only three elements in the whole XHTML 1.1 module set
    that use Block.model, so this closes the class rather than the case.

  • <math> is no longer accepted in an EPUB 2 document. OPS 2.0.1 has
    no MathML — the EPUB 2 schema set never includes a MathML grammar — so
    epubcheck reports <math> there as RSC-005, and the expected-element
    list it prints names svg and no math. Ours listed math, which was
    both a wrong suggestion and a missing error: MathML had been in the
    EPUB 2 element pool since that pool was first written, and was the one
    element in it with no basis in the EPUB 2 schemas. EPUB 3 is unaffected.

    The MathML content-model checks are deliberately not switched off for
    EPUB 2 to match: every <math> in an EPUB 2 document is now an error
    from the grammar itself, so the extra detail can only ever land on a
    document that is already invalid — and suppressing a check on the
    grounds that another one covers the case is the shape behind three
    earlier silent-skip defects.
