As far as i know LIDO, well, we do use their flight planning system, charts, engine out procedures and i guess their FMC databases as well. However, with Jepp they did code it the same way for us. Might be tailored, or just a difference between europe and the US. Heck, even in the old non-gps classics it was coded in 0.3, same as any other NPA. But back then we certainly bought tailored stuff from Jeppesen, their airport booklets (one small book with all charts in the correct order per airport) were great, much better than those chart binders our colleagues at other airlines used.
