The inclusions were removed with the following very crude script and the
resulting breakage was fixed up by hand. The manual fixups did either
revert the changes done by the script, replace a generic header with a more
specific one or replace a header with a forward declaration.

/**
|
|
* MODULE NOTES:
|
|
*
|
|
* This class does two primary jobs:
|
|
* 1) It iterates the tokens provided during the
|
|
* tokenization process, identifing where elements
|
|
* begin and end (doing validation and normalization).
|
|
* 2) It controls and coordinates with an instance of
|
|
* the IContentSink interface, to coordinate the
|
|
* the production of the content model.
|
|
*
|
|
* The basic operation of this class assumes that an HTML
|
|
* document is non-normalized. Therefore, we don't process
|
|
* the document in a normalized way. Don't bother to look
|
|
* for methods like: doHead() or doBody().
|
|
*
|
|
* Instead, in order to be backward compatible, we must
|
|
* scan the set of tokens and perform this basic set of
|
|
* operations:
|
|
* 1) Determine the token type (easy, since the tokens know)
|
|
* 2) Determine the appropriate section of the HTML document
|
|
* each token belongs in (HTML,HEAD,BODY,FRAMESET).
|
|
* 3) Insert content into our document (via the sink) into
|
|
* the correct section.
|
|
* 4) In the case of tags that belong in the BODY, we must
|
|
* ensure that our underlying document state reflects
|
|
* the appropriate context for our tag.
|
|
*
|
|
* For example,if we see a <TR>, we must ensure our
|
|
* document contains a table into which the row can
|
|
* be placed. This may result in "implicit containers"
|
|
* created to ensure a well-formed document.
