Can you supply some examples, and ideally the link to the astro documentation? I will then be happy to add it in.

A simple specfication can be found here https://docs.astro.build/en/basics/astro-syntax/ and here https://docs.astro.build/en/basics/astro-components/#component-structure.
Basically, the syntax is similar to Vue components.
