AttrParser(path_parser)

Attributes have two possible schemas 1. When an attribute has only one path `     <attr_id>: <attr_path>     # .. other attributes .. ` 2. `     <attribute_id>:         [resource_id]: <resource_id> (default is "default")         path: <attr_path>         [unique]: true|false (default is false)         [sorted]: none|ascending|descending (default is none)         [value_type]: unspecified|int|float|str|list[int]|list[str]|list[float] (default is unspecified)         [missing_values]: [<value0>, <value1>, ...]     `.
