Character position definition and scope:

A one-character alphabetic code indicates the family of braille to which the item belongs.  This is not the particular braille code.  It is the type of braille code used, representing different types of written symbols.  This position is also coded to identify the class of braille writing used for the text labels of cartographic or graphic items.

Up to two braille types may be indicated, or the cataloging agency may choose to encode only the predominant type.  Multiple codes are coded in order of predominance, if any.  If fewer than two codes are assigned, the codes are left justified and the unused position contains a # (blank).  Two fill characters ( || ) are used when no attempt has been made to code this data element.

Record requirements for National-level and Minimal-level records:  Optional.
