Background

XML (extended markup language) is the most recent common markup language. Before XML there was HTML. (hypertext markup language) The predecessor to HTML was the much more powerful SGML.

Markup consists of tags that add properties to sections of text. For example:

    <h2>Comments</h2>

As shown below, this is interpreted as marking the Comments text as a header of degree 2.

Comments

To make life easier for programmers handling these new formats, it's been suggested to have an XmlKit. I think we should instead have a MarkupKit. There would be add-ons that could parse different kinds of markup. Such add-ons could interact with the CharacterSetEncodingsForMarkup support in the proper way to ensure that the file is parsed and decoded properly.
