+### Special attributes
+
+Two special attributes are handled differently: `text` and `body`, these 
+are equivalent, the two names exist to make the semantics of macros simpler.
+
+If both attributes are defined `body` takes precedence over `text` and 
+both are overriden by a non-empty body, e.g. the following:
+```
+<slot slot text=text-attr body=body-attr>body</slot>
+```
+will resolve to `body`.
+
+The main difference from normal attributes is that the value of these is
+parsed in the same way as the element's body is. Thus, the following are
+identical:
+```
+<macro-name text="body text"/>
+
+<macro-name body="body text"/>
+
+<macro-name>body text</macro-name>
+```
+
+The values are parsed lazily, i.e. only the final value is parsed, the 
+overridden values are ignored.

+Define or fill a slot.

+First occurrence of a slot `name` will _define_ a slot and set its value 
+(fill it) with `text` if given.
+Each new occurrence of a name will override slot content.
+
+Only the first occurance of the `name` slot macro is displayed by default.
+
+Slot display can be explicitly controlled via the `hidden` and `shown` 
+keywords, if both are given `hidden` has precedence.

+Nested slots are processed in order of occurrence, i.e. a nested slot can 
+override it's parent's value.
