FormPath

Constructs a path from non-empty arguments, silently dropping every empty argument.

Use array when an empty array segment must be retained.

Permissively parses bracket notation into non-empty segments.

Plain text and bracket contents become segments. Empty bracket contents are discarded, stray ] characters are ignored, and an unterminated [ consumes the remaining text. Consequently, parsing and rendering do not round-trip array brackets or malformed input.

The path with no segments; its name and id are empty.
