Vladimir Dzhuvinov:

There are cases when one may want to do the discovery for Entities other than Leaf Entities.

> Federation Entity Discovery
>
> A process that starts with an Entity Identifier and collects a number of Entity Statements until the chosen Trust Anchor is reached. From the collected Entity Statements, a Trust Chain is constructed and verified. The result of the Federation Entity Discovery is that the Leaf Entity's metadata is constructed from the Trust Chain.

The “Leaf” in the last sentence should be removed.
