TABLE 8.73 Attributes of the <body> element
ATTRIBUTE DESCRIPTION
xmlns The default namespaces for elements within the rich text string. Must be xmlns="http://
www.w3.org/1999/xhtml"
xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0".
xfa:contentType Must be "text/html".
xfa:APIVersion A string that identifies the software used to generate the rich text string. It must be of the
form software_name:software_version, where
• software_name identifies the software by name. It must not contain spaces.
• software_version identifies the version of the software. It consists of a series of integers
separated by decimal points. Each integer is a version number, the leftmost value being a
major version number, with values to the right increasingly minor. When comparing
strings, the versions are compared in order. For example “5.2” is less than “5.13” because
2 is less than 13; the string is not treated as a decimal number. When comparing strings
with different numbers of sections, the string with fewer sections is implicitly padded on
the right with sections containing “0” to make the number of sections equivalent.
xfa:spec The version of the XML Forms Architecture (XFA) specification to which the rich text
string complies. PDF 1.5 supports XFA 2.0; PDF 1.6 supports XFA 2.2; and PDF 1.7 sup-
ports XFA 2.4.
