This is the first release of sgml-stream.

This release contains the core parts of our internal implementation of sgml-stream. We are switching over to the open source implementation internally, but this may take a couple more days. Initial experiments / partial migrations to the open source implementation have been successful. This core is a partial reimplementation in some key areas. Our internal implementation was just to tightly bound to our own code. We don't expect weirdness to occur if you would start using v0.2 today. However, we don't have systematic test coverage yet. We do have some core xhp behaviors specified in open-xhp-specification. This mostly pins down attributes, since we previously behave(d) differently from xhp-lib in some areas. Once we've imported the open source sgml-stream fully, any weird behaviors will probably be noticed and ironed out quickly.
