## Conventions

* All items and elements are listed in alphabetical order. Attributes are listed in alphabetical order with required attributes first. When there are multiple elements for the same item, there is no preference for any particular element over another, as long as the resulting markup is well-formed.
* Typical EBNF-style notation applies: `[ ]` indicates optional, `|` indicates alternation, `{ }` indicates repetition, etc.
* **bold** indicates a default value.

## Conventions

* All items and elements are listed in alphabetical order. Attributes are listed in alphabetical order with required attributes first. When there are multiple elements for the same item, there is no preference for any particular element over another, as long as the resulting markup is well-formed.
* Typical EBNF-style notation applies: `[ ]` indicates optional, `|` indicates alternation, `{ }` indicates repetition, etc.
* **bold** indicates a default value.
