-Any numeric key is treated as an attribute ID, and specifies the handling for
-that attribute. Attribute ID zero is treated as a wildcard, and will match any
-attribute without an explicit handler. The handler can be specified as a sub
-(as for attribute ID 13 in the example above) or as an arrayref C<[$minsize,
-$sub]>. In the latter case, the sub is only called when at least C<$minsize>
-bytes of data are available for the attribute, or at the end of the attribute
-data.
