CIASAttributeEditor::SetAttributeValue

	Most of the time, before you can use an editor's functionality,
	you need to pass it a pointer to the value the editor's methods
	e.g. will modify.

	Note that this is not always the case, for example, to gather information
	about the attribute's vendor, you need not always specify a value.

	Pass a NULL pointer to SetAttributeValue to disassociate the
	editor from any value.

CIASAttributeEditor::get_VendorName

	For most attributes, vendor information is stored in the AttributeInfo.
	However, for some attributes, e.g. the RADIUS vendor specific 
	attribute (ID == 26), vendor information is stored in the value of the
	editor itself.
	
	For this reason, UI clients should always query an IASAttributeEditor for vendor 
	information rather than the AttributeInfo itself.

	In the default implementation here, we will query the AttributeInfo 
	for this information.  Some derived implementations of IASAttributeEditor
	(e.g. IASVendorSpecificAttributeEditor) will parse the value of the
	attribute itself to procide this info.
