You note that there's no "Alpha" number and you give the xml:id as
<msItem xml:id="B.19.l">
It would be good to identify the B.19.l number as being a reference to the 1954 "Raghavan List".
The text of this Raghavan List has never been made publicly available, and it would be a mistake to let the Raghavan numbers escape into the public domain if at all possible, since readers would inevitably start using them for ordering and reference. These are obsolete numbers that, after accessioning ic complete, will have only historical interest.
Nevertheless, the Raghavan List has been transcribed as a LaTeX (>PDF) file and should be made available internally at the WL, especially if these XML files are going to refer to it.
The nomenclature "Alpha number" might also be reconsidered. I always referred to "the Greek-letter sequence". Whichever naming convention is chosen, it should be as clear as possible and be used consistently.
