/*
* The following classes implement extended Save As MTHML functionality.
* Access to the extended functionality is controlled by new MECD_ flags
* defined in mimeole.h. Clients of the C API in this module should notice
* mimimal change in its behavior. ( limited to the additional inclusion
* table and table cell background images ).
*
* The root idea is that of a collection packager, which takes a subset
* of the document.all collection, filters the elements of that subcollection,
* and marshall's the element data into the MIMEOle document This is patterned
* after the existing PackageImageData routine, and relies heavily on
* HrAddImageToMessage, which is much more general than its name implies.
*
*
* Stylesheets introduce some repetition, as the stylesheet OM is similar,
* but not similar enough, to support common base classes specialized via
* templates.
*
* The process of adding new packagers is pretty straight-forward.
* [1] (a) if the packaged attribute is a complete URL, derive from CCollectionPackager
* (b) if the attribute is a relative URL, derive from CRelativeURLPackager
* [2] Implement InitFromCollection. Have it call _InitSubCollection() with the tag name.
* See CImagePackager::InitFromCollection() as a simple example.
* [3] Implement _GetTargetAttribute() to return the attribute you want to package.
* You may want to add the string constants for [2] and [3] to htmlstr.h
* [4] Define an MECD_ control flag, if the thing you're packaging is new.
* [5] Add a local var of your packager type to CDocumentPackager::PackageDocument.
* [6] Follow the pattern of the other packagers in CDocumentPackager::PackageDocument
*
* For elements with multiple persisted attributes, it's dealer's choice as to how
* to approach it. Write seperate, simpler packagers for each attribute or write
* one packager that deals with all of the target element's attributes.
