Samples that circulate on the +%D web are often border cases and torture test and don't have much to do +%D with real live. Another complication lays in the inheritance model: +%D some of the attributes are inherited. This also leaves some room for +%D interpretation, for instance do values that are used at a certain +%D point migrate downwards or not. +%D +%D The \CONTEXT\ \XML handler can deal with attributes in several ways +%D and for this purpose I have played with a few experimental mechanisms +%D just to end up with the existing begin/end mechanism combined with +%D a recursive attribute resolver which means that one has to implicitly +%D ask for an inherited attributes. This approach is probably one of the +%D most efficient ways of dealing with formatting objects in \CONTEXT, +%D unless of course I start adding rather specific support to the kernel. +%D +%D This module is rather experimental. More information about its usage +%D can be found in the \FOXET\ manual. + +%D Since we're not dealing with the fine points of typesetting here, we +%D can safely ignore \TEX's warnings about overful or underful boxes. + +\dontcomplain + +%D We will use fonts that have the characters in the normal (ascii) +%D slots.

Don't ask me why, but +%D formatting objects are not a fresh start but a mix of existing +%D technologies. Color support is poluted by cascading stylesheets. +%D +%D Because hexadecimal color specifications are not enabled by +%D default, this feature has to be enables by loading the appropriate +%D color module.

We also need to deal +%D with nested elements (for instance blocks) or a sequence of similar +%D ones, while we may not always want to use grouping. As a result, the +%D next series of definitions and macros are quite ugly.
