In repository.cnd:

[hippo:remodel] mixin

• hippo:uri (string)

[hippo:field] > nt:base

• hippo:name (string)

[hippo:templatetype] orderable
+ hippo:nodetype (hippo:handle) mandatory
+ hippo:template (hippo:handle)
+ hippo:prototype (nt:base)

[hippo:namespace] > nt:base
+ * (hippo:templatetype) = hippo:templatetype

[hippo:namespacefolder] > nt:base
