"value".

<p>
A map. The parameters specify the allowed keys in the map.
<br />
Each parameter is a association tree that describes one
possible key. The name of the tree is the key itself, and
the second level of the tree can have "doc" and "type"
attributes for that key.
<br />
When the special key name "allow-other-keys" is present,
all keys are allowed; otherwise, only the specified keys
have any meaning and additional keys are an error.
<br />
When no parameters are given, all keys are allowed.

<dt class="hdlist1">
<strong>association-tree</strong>
</dt>
<dd>
<p>
A tree made from nested lists, used to associate
(hierarchical) keys with values.
<br />
For example, the association tree
<br />
[ "foo", [ "bar", 12 ], [ "baz", 42 ] ]
<br />
associates "foo", "bar" with 12 and "foo", "baz" with 42.
<br />
Association trees are often used as a simple "Nano DOM" for
XML documents.
<br />
Formally, a association tree is a list whose first element is
a string, and whose rest elements are either association
trees, or a single value.
<br />
The "name" of a association tree is the first element of its
top-level list.
<br />
As a special case, a association tree with just a name and no
other elements can be abbreviated by just stating the name as
a string. E.g., the following two values are equivalent when
considered as a association tree:
<br />
"foo"
[ "foo" ]

This is the base type for enumerations of fixed strings. The
parameters describe the possible values.

Each parameter is a association tree that describes one of
the choices. The name of the association tree is the
string for the choice itself and the second level of the
tree can have a "doc" attribute for that choice.

<p>
This is the base type for enumerations of fixed integers.
The parameters describe the possible values.
<br />
Each parameter is a association tree that describes one of
the choices. The name of the association tree is a
symbolic name for the choice itself and the second level
of the tree must have a "value" attribute that gives the
numerical value of the choice in decimal. A choice can
also have a "doc" attribute, of course.
