I disagree on this. The tag is metadata and metadata should be as strong =
a=20
contract as code itself. The only difference between tags and codebased=20
metadata schems is that codebased metadata schemes require;
* that the .class be loaded to get at metadata
* that the supporting metadata classes be accessible to classloader

We have different opinions. I dont believe that "We can alter the values =
of=20
the names without affecting the runtime compatibility of the code." is tr=
ue.=20

Metadata interfaces are not work interfaces and thus never get exposed to=
=20
clients and thus they should have 0 effect on client code - only on the=20
client-container contract. This is exactly the same thing as metadata.
