If program A writes the string attributes of the h5md group using a
variable-lengths string datatype, and program B reads the string
attributes of the h5md group using a fixed-length string datatype,
the HDF5 library will return an error.

Unless you have a good reason why fixed-length string datatypes
are important for the storage of the existing H5MD attributes,
I see no point in provoking these incompatibilities.
