This is a required part of every HTML document which identifies or summarizes
the content found within. A suggested size limit for titles is 256 characters.
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
'Ti' element - "title of the book".) SDA also allows attributes
and values from the original element to be used in the new SDA element
where necessary.
