The identity of this mark has been debated in a couple of forums. I don't 
recommend it for the kholam male, though, because the upper dot is often 
larger and higher then the holam mark.
We're using the upper dot for two purposes: in Masoretic notes and to 
indicate Hebrew letters used as numbers. In both cases the upper dot is 
visually centered above the consonant.
In the past, SIL were using it for above puncta extraordinaria: which occur 
only a few times in the Biblical text, and whose signifigance is debated by 
scholars. I think this is a misuse, since there is no corresponding below 
puncta extraordinaria in the Unicode Hebrew block. SIL seem to have come 
around to this view, and we are both currently using U+0307 and U+0323 for 
the above and below puncta, despite rendering problems in many current 
apps. Because the puncta are typically larger and further above and below 
the consonants than the upper and lower dots used for Latin script, and may 
also not be round, we favour separately encoding the two puncta marks in 
the Hebrew block.

surrounded by a scrum of furiously scribbling print
journalists will stand for some time as the apogee of
media cannibalism.
