Automatic transformation of XML namespaces/Cheat sheet

This are some of the opportunities our software opens:
 * freely intermix tag sets of different sets of tag semantics (using XML namespaces), without disturbing each other (such as by name clash) in the global world
 * add your new tags to HTML (and other XML-based formats)
 * get rid of using HTML in future Web, switch it to proper semantic XML formats
 * make XSL-format based browsers with automatic generation of XSL from other XML formats
 * make automatic coloring of source listings (for example)
 * add macroses and include (such as by XInclude) other files in XML
 * intermix different XML formats, with intelligent automatic processing of the mix
 * embed one XML format in another one
 * automatically choose the order of different XML converters applied to your mixed XML file
 * make browsers to show your XML in arbitrary format
 * make processing XML intelligent (with your custom scripts)
 * integrating together XML conversion and validation scripts written in multiple programming languages
 * associating semantics (such as relations with other namespaces and validation rules) to a namespace
 * semantics can be described as an RDF resource at a namespace URL (or a related URL)
 * file transformation with an automatically found "chain" of several conversions between different formats
 * TODO
 * many more opportunities
 * integrate all of the above in single command
 * (in the future) make it also a HTTP(S) proxy server
