What this means

Link types come from GS1's published registry. A gs1: name that is not in that registry emits a relation URI that dereferences to nothing, inside the one namespace the conformance suite inspects.

Why it usually happens

A typo, or a type read out of a draft of the vocabulary that never shipped as one.

What to do

Choose the type from the list the link editor offers. The registry is public, and the glossary's link type entry cites it.
