- If no parameters are specified, this returns an associative array of all
name/value pairs.
- If both $name and $value are set, then this will set the attribute name/value
pair for all items in this object.
- If $name is set, and is an array, then
all attributes in the array will be set for all items in this object.
- If $name is a string and is set, then the attribute value will be returned.
When an attribute value is retrieved, only the attribute value of the FIRST
match is returned.
