Can we have a sample file?

Sample files, as requested: http://adedemo.com/Title-XHTML.asp?InventoryID={0267D86F-EDAC-4B2F-8763-FE088111B5AB} http://adedemo.com/Title-XHTML.asp?InventoryID={638B830A-34D6-47A9-96A7-57675F1582FF} http://adedemo.com/Title-XHTML.asp?InventoryID={78BB2A25-5CB7-4CB8-8270-A8A1CC44C9CC}

This is not a bug. Example files reference transitional XHTML 1.0 DTD
( http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ). OPS 2.0 requires XHTML
1.1 ( http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd ). When transitional XHTML 1.0 DTD
is processed by the parser, it pulls in default value "none" for the clear attribute:

Then perhaps the epub checker could explicitly say that the wrong DTD is being used,
or that a DTD is not needed. Or both.

I encountered the same issue in a different context. I agree with with comment #4. It would be better to get a more precise error or warning message.

<!ELEMENT br EMPTY> <!-- forced line break -->
<!ATTLIST br
%coreattrs;
clear (left|all|right|none) "none"

This value conflicts with XHTML 1.1 validation which does not allow that attribute.
Files should be fixed either to reference correct DTD (XHTML 1.0 strict - not
transitional - might work) or not reference DTD at all (namespace declaration is
sufficient for OPS).

Status: Invalid
