dtd-version

Version of the Tag Set (DTD)

Version of the BITS Tag Set that should be used to validate this book or book part.

Remarks

Best Practice: This attribute should be set on every document instance explicitly, even when using the XSD or RNG version of BITS. This is a “fixed” attribute (meaning that the value is set via a parameter entity in the DTD; thus, an author or editor cannot change it) that should change every time the BITS Tag Set changes version number.

Used on Elements: <book>, <book-part-wrapper>

ValueMeaning
2.0The version of the BITS Tag Set that is being used.
Restriction@dtd-version has a fixed value which may not be changed in the document.
