Groups of 8, 4, and 4 digits, and a subset of eight groups of 2 digits, with each group prefixed by "0x" or "0X", and separated by commas. The entire GUID, as well as the subset, is enclosed in matching braces:

All braces, commas, and "0x" prefixes are required. All embedded spaces are ignored. All leading zeroes in a group are ignored.

The digits shown in a group are the maximum number of meaningful digits that can appear in that group. You can specify from 1 to the number of digits shown for a group. The specified digits are assumed to be the low order digits of the group.
