8 Unique identifier for a custom-built HTML definition. If you edit
9 the raw version of the HTMLDefinition, introducing changes that the
10 configuration object does not reflect, you must specify this variable.
11 If you change your custom edits, you should change this directive, or
12 clear your cache. Example:
15 $config = HTMLPurifier_Config::createDefault();
16 $config->set('HTML', 'DefinitionID', '1');
17 $def = $config->getHTMLDefinition();
18 $def->addAttribute('a', 'tabindex', 'Number');
21 In the above example, the configuration is still at the defaults, but
22 using the advanced API, an extra attribute has been added. The
23 configuration object normally has no way of knowing that this change
24 has taken place, so it needs an extra directive: %HTML.DefinitionID.
25 If someone else attempts to use the default configuration, these two
26 pieces of code will not clobber each other in the cache, since one has
27 an extra directive attached to it.
30 You <em>must</em> specify a value to this directive to use the
31 advanced API features.
