Is RVAD tag supported?

[Pingaware]

I've been doing one of my semi-regular look at tag inspector for lots of my files, and I've found a few have RVAD (which according to the IDV2.3 spec is Relative Volume Adjustment). I have no idea where it's come from. MB is still my only music player, so if this isn't needed (given I have all the usual MB ReplayGain stuff enabled and set) I will simply delete it. Can I?

In the tag editor settings tab, the volume adjustment there reads and writes RVAD

Ah, things I never knew! I've never intentionally set that, so I feel safe deleting any instances of it.

Thanks as ever Steven!
