Some problems with (X)HTML 5 specification

[GoogleCodeExporter]

VERSION:

3.0

STEPS TO REPRODUCE:

1. check with epubcheck the attached file (it's the printable version of the 
"autism" page of wikipedia, converted to epub with Calibre)
2. read the errors ^^

RESULT:

epubcheck reports the errors:

a. attribute "class" not allowed here [in "html" tags]
b. element "script" missing required attribute "type"
c. value of attribute "dir" is invalid ["auto"]
d. attribute "srcset" not allowed here [in "img" tags]
e. attribute "role" not allowed here [in "div" tags]

EXPECTED:

None of these errors should be displayed. In (X)HTML 5: 

a. "class" attribute is allowed in any tag
b. attribute "type" is no longer required for "script" tags
c. attribute "dir" can have value "auto"
d. "srcset" is a proposed html extension for images: 
http://www.w3.org/html/wg/drafts/srcset/w3c-srcset/
e. "role" attribute seems to be reintroduced in HTML 5: 
http://www.w3.org/TR/role-attribute/

You generated an EPUB 2 containing XHTML 1.1 content using Calibre, so all the 
errors are valid.

You need to convert the content to EPUB3/XHTML5 if you want it to validate as 
such.

Right. In this case epubcheck, I think, should alert about the inconsistency 
between the epub version and the doctype of XHTML files, since it's preferable 
that you'll convert the epub 2 to an epub 3 instead of convert all xhtml 5 
documents to a previous xhtml specification.

In theory this is another issue, you can close this bug and open another one if 
you want :)

But no doctype was specified in these files that I found, so epubcheck is doing 
exactly what it should for an epub declared as 2.0 in the OPF.

If the html5 doctype had been specified, then I agree it would be useful to at 
least report an unexpected doctype.

Well, the fact the doctype is removed is a calibre bug. Anyway I think 
epubcheck should alert you the doctype is missing, since html 5 specs requires 
it:
