* Standard events for HTML5.
|

|
|
*
|
||
|
|
* This is roughly analogous to a SAX2 or expat-style interface.
|
||
|
|
* However, it is tuned specifically for HTML5, according to section 8
|
||
|
|
* of the HTML5 specification.
|
||
|
|
*
|
||
|
|
* An event handler receives parser events. For a concrete
|
||
|
|
* implementation, see DOMTreeBuilder.
|
||
|
|
*
|
||
|
|
* Quirks support in the parser is limited to close-in syntax (malformed
|
||
|
|
* tags or attributes). Higher order syntax and semantic issues with a
|
||
|
|
* document (e.g. mismatched tags, illegal nesting, etc.) are the
|
||
|
|
* responsibility of the event handler implementation.
|
||

|

|
|
* See HTML5 spec section 8.2.4

* an integer, the parser will switch TEXTMODE patters according to the int.
|

|
* The HTML5 standard requires that the builder is the one that initiates this

|

|

* implementation returns Tokenizer::TEXTMODE_RAW, then the tokenizer will
|
||
|
|
* switch into RAW text mode and consume data until it reaches a closing
|
||
|
|
* `script` tag.
|
||
|
|
*
|
||
|
|
* The textmode is automatically reset to Tokenizer::TEXTMODE_NORMAL when the

||
|
|
* closing tag is encounter. **This behavior may change.**
