What is it?
This is THE top level container element for an HTML document. It specifies that the content of the document is text with HTML markup tags. The content of an HTML document is a HEAD element which contains the title of the document plus other information ABOUT the document. Following the HEAD element comes the visible content of the document in the BODY element. Alternately, an author may specify a FRAMESET series in place of the BODY element that enumerates the layout of sub-documents to be contained in the master document.

Description:
This is an SGML Document Access (SDA) attribute. SDA attributes are designed to transform HTML (and other SGML-based documents) to the ICADD DTD - which is used in creating accessible documents for users with visual disabilities (rendering in Braille, large print, speech synthesis, etc.) The attribute value specifies the name of the element to convert this element to in the SDA element group (in this case the 'Book' element - "highest level element for document".) SDA also allows attributes and values from the original element to be used in the new SDA element where necessary.
Value: Book (Denotes 'highest level element for document' in SDA.)
