* A collection of attributes to associate with an element in a document.
|
|
* Since these are typically used to associate character and paragraph
|
|
* styles with the element, operations for this are provided. Other
|
|
* customized attributes that get associated with the element will
|
|
* effectively be name-value pairs that live in a hierarchy and if a name
|
|
* (key) is not found locally, the request is forwarded to the parent.
|
|
* Commonly used attributes are separated out to facilitate alternative
|
|
* implementations that are more efficient.
