This is not true anymore. :) DataCite's content negotiation covers ETH as
well. 

However metadata (in DataCite metadata schema) is currently only available
for about 60% of ETH's dois.

Checking for HS_SERV in the prefix handle is most reliable one at the
moment.

We have only those two already mentioned (0.SERV/TIB, 0.SERV/ETH), the
latter one since 2009. There are no plans at all to change this status quo.
