These two syntaxes should express the exact same set of Bikeshed anchors. The first is simple JSON, the second is a custom nesting syntax.

Some notes on the second:

• Anchors are defined by the leaf nodes, accumulating values from the path down. You can express any anchor purely through nesting, but when the nesting doesn't add anything, you can collapse values into a single line with a semicolon separating them.
• The urlPrefix key is accumulative; if multiple are encountered as you descend the nesting, they concatenate. The final url key is then concatenated to the accumulated urlPrefix.
• If there is no url key, one is generated from the text key by doing standard IDification. If the urlPrefix doesn't contain a # character, one is inserted between the prefix and the generated ID.
• Each anchor must contain a type, a text, and one or both of urlPrefix and url. It may contain a for.
