This type supports time resolution at the millisecond level It is further constrained to always use the timezone designator "Z" indicating GMT. Quantities of this type can optionally use 3 digits of fraction after the second to represent the milliseconds. If absent, it is assumed the millisecond component is ".000". Example: 1999-05-31T13:20:00.561Z This type supports time resolution at the microsecond level. It is further constrained to always use the timezone designator "Z" indicating GMT. Quantities of this type can optionally use 6 digits of fraction after the second to represent the microseconds. If absent, it is assumed the microsecond component is ".000000". Example: 1999-05-31T13:20:00.561843Z An IP version 4 address in dotted notation decimal. Example: 15.13.120.22 An IP version 6 address in colon separated 2 byte block hexadecimal notation. Example: FEDC:AB19:12FE:0234:98EF:1178:8891:CAFF An IP version 4 or 6 address A universal unique id in hex dash notation. Example: f81d4fae-7dec-11d0-a765-00a0c91e6bf6 IEEE 802(R)-2001 A Medium Access Control address in hypen separated 1 byte block hexadecimal notation. Example: 0F-2C-D0-44-2E-09
