+
+       Additional referenced assemblies can be specified by adding 'Reference' tags. 
+       These libraries will not be examined and registered with Excel as add-in libraries, 
+       but will be packed into the -packed.xll file and loaded at runtime as needed.
+       For example:

+       <Reference Path="Another.Library.dll" Pack="true" />
+
+       Excel-DNA also allows the XML for ribbon UI extensions to be specified in the .dna file.
