Spec's Expressiveness

# Problem

Currently, you can easily come into wrong assumptions that something would work in the specification.

We need to find minimal requirements to implement a sane spec plugin.

# Constraints

# Assumptions

# Considered Alternatives

# Decision

- no defaults for `sw/_/key` specifications (default will not work for `ksLookup(/sw/sthg/key)`)
- plugins are not allowed to create keys (may change in future; depends on plugin positions)

The spec plugin should yield errors when it detects such situations.
