An HTML snippet that specifies hints for the user, help links, help graphics, and other supplemental information that varies per characteristic set. In GetProductSearchPage, one DataElement value contains a hint (including an empty HTML achor element), one DataElement value may contain a URL to insert into the HTML anchor as the href value, and one DataElement value may contain a URL that eBay uses as a help graphic. If no value is available in the meta-data, a dash ("--") is returned instead. Usage of this information is optional and may require developers to inspect the information to determine how it can be applied in an application. Because this is returned as a string, the HTML markup elements are escaped with character entity references (e.g.,<a href=""><Attributes>...). See the appendices in the eBay Web Services guide for general information about string data types.
Matches the AttributeSetID associated with a response returned from the same call that returned the data element set. As calls like GetProductSearchResults can perform batch searches, this ID helps you determine which attribute set the data element set is associated with.
