[config-dev] BNF example

[Laird Nelson <ljnelson@xxxxxxxxx>]

Hello; just closing a tiny loop from last week's discussion:

Someone (I think it was Roberto?) on the discussion last week was asking if a specification such as Jakarta Persistence actually defined the BNF for its query language. I wasn't sure at the time but here's the link: https://jakarta.ee/specifications/persistence/3.1/jakarta-persistence-spec-3.1.html#bnf

So the answer is yes.

As a counter example, EL does not have a BNF grammar explicitly spelled out, but effectively has one in English form: https://jakarta.ee/specifications/_expression_-language/4.0/jakarta-_expression_-language-spec-4.0.html#el-expressions

Best,

Laird
