Further information

1. Attribute values are stored as text objects: the versions of this procedure accepting other types perform the conversion implicitly.

2. Attributes are nodes of type XML_ATTR: procedure setvalue may also be used to change the value of an attribute.

3. Setting an empty value to an attribute does not remove this attribute from the attribute list of the element. Use delattr for this purpose.
