slicc: support for multiple cache entry types in the same state machine
To have multiple Entry types (e.g., a cache Entry type and
a directory Entry type), just declare one of them as a secondary
type by using the pair 'main="false"', e.g.:
structure(DirEntry, desc="...", interface="AbstractCacheEntry",
main="false") {
...and the primary type would be declared:
structure(Entry, desc="...", interface="AbstractCacheEntry") {
