<h2>Attribute Functions</h2>

<h3><a id="attribute"><code><nowiki>(attribute [handle (or/c ihandle? #f)] [name (or/c symbol? string?)]) → (or/c string? #f)</nowiki></code></a></h3>

Gets the value of an attribute. If the handle is <code>#f</code>, a global
attribute is accessed. Attribute values are always returned as strings,
which is the native form in which they are stored.

Gets a list of all user-defined attributes set on a given handle. If
the handle is <code>#f</code>, the global attributes are examined.
