After review, there are cases where having common requirements for namespaces and identifiers creates contention between applications. One example is that it is nice to have namespaces comply with domain name requirement, but that does not allow underscores, which are required for certain identifiers. The namespaces validation has been reverted to be in line with RFC 1035. Existing identifiers has been modified to allow simply alpha-numeric identifiers, while limiting adjacent separators. We may follow up tweaks for the identifier charset but this split should remove the hard decisions. Signed-off-by: Stephen J Day <stephen.day@docker.com>
