Re: missing intent concept?

Wow… the whole concept seems to be missing, indeed. I guess  
 | y > should be listed as “vector”,
  < x | as “co-vector" or “functional",
  < x | y >  could be listed under the existing title "inner-product” (or under a synonymous new one “scalar-product”),
 | y >< x | stands for “dyad” or “dyadic-product"
all in linear (or vector) algebra (and physics, where this Dirac notation comes from).

Much to my surprise, I didn't find it listed in either the core  <https://w3c.github.io/mathml-docs/intent-core-concepts/>or open  <https://w3c.github.io/mathml-docs/intent-open-concepts/>concept lists. Does it have some other name, or was it overlooked?
