Im wondering if these documents are different types:
1. Errat Notice, PR141-PRDC-007452, v9.0, 2008
2. Software developers Errata Notice, ARM-EPM-039114, v2.0, 2014
From my point of view, these documents are the "same" (of course in another revision).
a) But why do the have a complete other doc-id?
b) And why is v9 from 2008 and v2 from 2014?
Are these documents finally not comparable?
