Explicitly sets the ID of a macro.
In OurBigBook Markup, every single macro has an ID, which can be either:
  • explicit: extracted from some input given by the user, either the id argument or the title argument. Explicit IDs can be referenced in Internal cross references and must be unique
  • implicit: automatically generated numerical ID. Implicit IDs cannot be referenced in Internal cross references and don't need to be unique. Their primary application is generating on hover links next to everything you hover, e.g. arbitrary paragraphs.
The most common way to assign an ID is implicitly with automatic ID from title conversion for macros that have a title argument.
The id argument allows to either override the automatic ID from title, or provide an explicit ID for elements that don't have a title argument.
