Attr.ClassUseCDATATYPE: bool/nullDEFAULT: nullVERSION: 4.0.0--DESCRIPTION--If null, class will auto-detect the doctype and, if matching XHTML 1.1 orXHTML 2.0, will use the restrictive NMTOKENS specification of class. Otherwise,it will use a relaxed CDATA definition. If true, the relaxed CDATA definitionis forced; if false, the NMTOKENS definition is forced. To get behaviorof 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 ofclass was NMTOKENS, as specified by the XHTML Modularization (representingXHTML 1.1 and XHTML 2.0). The DTDs for HTML 4.01 and XHTML 1.0, howeverspecify class as CDATA. HTML 5 effectively defines it as CDATA, butwith the additional constraint that each name should be unique (this is notexplicitly outlined in previous specifications).--# vim: et sw=4 sts=4
