Do we know what this really means in practice? Surely the Grauniad thing saying 1:10000 but not 1:25000 has got to be wrong (because, er, duh).
And what does 'down to 1:10000' mean with vector data, anyway?

Maps are drawn differently at different scales (e.g. position of text so it doesn't obscure features). So there is a different set of data for each published scale. My experience with OS data was quite a few years ago, but it may be that there is different coding for lines and point features at the different scales, which shows their non-digital heritage.
