Sorry for vasting your time. The API works nicely as is.

After reading the  README.developper (and not just the developer-guide.pdf)
I understodd how to do the BCD I wan't. Define the field as FT_UINT32 and
use it by:
proto_tree_add_uint(tree, hf_apacs_stan_type, tvb,
    offset, length, tvb_get_bcd(tvb, offset, length));

How elegantly simple
