I was trying to allow SharedBaseAddress to turn off CDS and not give an error.  What you suggested is easier.  I had a variant of this at one point with klass_decode_node() returning false but not setting decode_node also would work.

Thanks for looking at this.  I'm going to continue to subsume your PR in this one.
