Subject: [rohc] maximum_expansion_size

Hi,

Just a minor comment,

If compression is applied on encrypted messages the result might instead be an expansion of the message (depends of course on the algorithm). Anyway, if this parameter is set to anything else than zero it might result in no output from SigComp. 
I just wonder if we should put a note along with description of the maximum_expansion_size regarding this:

"Note: If encryption is applied before compression, the resulting message after compression might instead be expanded. This needs to be considered when setting the maximum_expansion_size"

Perhaps this should go into the UDVM user guide instead?
Or perhaps this is so uncommon that we do not need to mention it all?
