Edit File: Attr.ClassUseCDATA.txt
Attr.ClassUseCDATA TYPE: bool/null DEFAULT: null VERSION: 4.0.0 --DESCRIPTION-- If null, class will auto-detect the doctype and, if matching XHTML 1.1 or XHTML 2.0, will use the restrictive NMTOKENS specification of class. Otherwise, it will use a relaxed CDATA definition. If true, the relaxed CDATA definition is forced; if false, the NMTOKENS definition is forced. To get behavior of HTML Purifier prior to 4.0.0, set this directive to false. Some rational behind the auto-detection: in previous versions of HTML Purifier, it was assumed that the form of class was NMTOKENS, as specified by the XHTML Modularization (representing XHTML 1.1 and XHTML 2.0). The DTDs for HTML 4.01 and XHTML 1.0, however specify class as CDATA. HTML 5 effectively defines it as CDATA, but with the additional constraint that each name should be unique (this is not explicitly outlined in previous specifications). --# vim: et sw=4 sts=4
