+%D We define color groups having equal gray scale values by either reducing 
+%D their rgb values to darken them or by adding equal amounts of $r=g=b$ to 
+%D lighten them.
+%D
+%D \startformula
+%D s = .3r + .59g + .11b
+%D \stopformula
+%D
+%D By the way, \CONTEXT\ has always used this formula internally when colors 
+%D are converted to gray.

+
+    Right from the start the ConTeXt user interface was sytematic enough to be described using a
+    common framework. First it was done in the TeX language at the top of the files where features
+    were implemented. Later we switched to XML where all definitions were moved to one file. That
+    file could be translated to different user interfaces.
+
+    The current XML files are a follow up on this. Instead of one big file we now have many small
+    files, and support for shared (XML) definitions has been extended. Many more commands are defined,
+    including those considered low level. There are no longer translated files needed but you can
+    still generate them.
+
+    These files can be used to generate overviews (see x-setups-*.mkiv) but also for generating
+    information for text editors. We also use them for the (local) help service.
