The format of the response can differ depending on set flags.

This chapter describes flags that can be applied to units and parts of resulting JSON which they are responsible for. If you specify several flags, then parts will be gathered into one JSON.

Unit flags:

Flag - 0x00000001

{
	"mu":<uint>,	/* measure units: 0 - si, 1 - us, 2 - imperial */
	"nm":<text>,	/* name */

	"id":<uint>,	/* unit ID */
	"uacl":<uint>	/* current user access level for unit */
}

Flag - 0x00000002

You can store any data you need in custom properties.
