WHAT IT'S USED FOR:
Advanced XML
The Attribute is an identifying attribute for the Element. This should be the full text of the name and value for the attribute, as it appears in the XML. e.g. sound="pop".
An entry here is not required unless you need to distinguish between different instances of the same element. For instance, in MARC XML the primary element is called 'datafield', Each datafield is further qualified with a tag attribute number. eg <datafield tag= "245"> contains document title information, whereas <datafield tag="260"> contains publication information.
WHERE TO FIND IT:
The Field Mapping page of the XML Import Configuration Window.
HOW TO USE IT:
Attribute is a text field. Just key in data, or copy it into the field from another source.
