You show us how to define a hyperlink in your example. How would we define the more simple, bookmark (to a location within the same workbook, but different worksheet). I don't think we need URI for this?
If there is no simple way to do this, can you give an example of how we can jump into XML of a selected worksheet and add the new nodes for a link as OOXML would do in Excel '07
<hyperlink ref="A5" location="'0 - 9'!A1" display="Artist Categories"/>
