*S*mall, *U*ncomplicated *X*ML.
This is a very simple implementation of XML/HTML as a network
protocol. It is not at all clever. Its main features are that it
does not:
- support namespaces
- mung mnemonic entity references
- validate
- perform *any* external actions (such as fetching URLs or writing files)
under *any* circumstances
- has lots and lots of horrible hacks for supporting broken HTML (as an
option, they're not on by default).
