epubcheck 5.0.1 for EPUB2: content model for XHTML1.1 del and ins?

[Doktorchen]

Looks like version 5 gets the content modell for del and ins wrong for EPUB2 using XHTML1.1.
XHTML 1.1 allows 'flow mix' - block and inline, epubcheck 5.0.1 does not want block.

Something like

<del datetime="2011-09-02" 
     cite="#Z">
<h1>Title Old</h1>
</del>
<ins datetime="2011-09-02" 
     cite="#Z">
<h1>Title New</h1>
</ins>

results in:

Validating using EPUB version 2.0.1 rules.

Same test with EPUB3/HTML5 results in no messages.

You use backticks to escape markup. See https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#quoting-code

Looks like a bug in the schema, I'll look into it.
