"Optional fields are usually displayed as TAG:TYPE:VALUE; the type may be one of A (character), B (general
array), f (real number), H (hexadecimal array), i (integer), or Z (string)."
however there is C,I,S, and the notion that B is combined with the types is not immediately obvious from the sentence. somewhat unclear what H is also.
digging deeper into cross references from BAM/CRAM might reveal more clarity, but perhaps even explicitly linking to those docs from SAMtags could help
