+Containers
+**********
+
+Upon request |rstcontext| now supports another kind of
+directive, namely containers_.
+Due to their being defined explicitly in terms of HTML,
+*containers* lack a corresponding construct in |CONTEXT| (or
+|TEX| for that matter).
+Some parts of |CONTEXT| (e. g. ``\framed``) come quite close with
+respect to functionality as well as generality.
+However, none of the candidates alone covers the entire spectrum
+of functionality that containers_ are supposed to.
+For that reason the implementation leaves them essentially
+undefined.
+
+If an explicit name is specified, then the ``container``
+directive maps to the environment of that name.
+Anonymous containers are interpreted as a |TEX| group.
+Any text block inside the element is treated as ordinary
+paragraph.
+In below example the content will be handled as if between
+``\startxyzzy`` and ``\stopxyzzy``, where it is up to the user to
+define the *xyzzy* environment::
+
+    This is a paragraph.
+
+    .. container:: xyzzy
+
+        whatever
+
+        foo **bar** baz
+
+    This is another paragraph.
+
+The middle part translates to |CONTEXT| as follows::
+
+    \start[xyzzy]%
+    whatever
+
+    foo {\sc bar} baz
+    \stop
+
+Note that the ``\start[foo]``/``\stop``-environment is equivalent
+to ``\startfoo``/``\stopfoo``, except that the environment
+doesn’t actually need to be defined.
+
+.. caution::
+    Support for the *container* directive is considered
+    experimental.
+    Suggestions for improving or extending the current
+    implementation are always welcome.
