Localised URL mistakes in the defaultpresets.xml

[DeeHants]

While creating my own preset file, I created an XSD schema for it, and noticed several mistakes in the defaultpresets.xml.

I've attached a patch based on r6326

Transport/Railway/Rail/voltage has the length attribute spelt incorrectly.
Facilities/Education/Driving School/license_classes should be a combo not a text as it has values.
Facilities/Facilities/Fire Hydrant/fire_hydrant:count shouldn't have a blank values tag as it's a text.

r6325 also seems to have introduced a couple of oddities with regards to zh-hans.href and zh-hant.href on:
Highways/Barriers/Toll Booth
Highways/Barriers/Wall
Transport/Car/Fuel
Transport/Public Transport (legacy)/Bus Stop
Facilities/Accommodation/Alpine Hut
Facilities/Food+Drinks/Café
Facilities/Food+Drinks/Bar
Facilities/Culture/Place of Worship
Facilities/Facilities/Toilets
Facilities/Facilities/Bench
Geography/Geography/Peak
Geography/Land use/Cemetery

While these are all linked to localised pages on the wiki, they are also incorrect.

I'll also attach my current schema to another ticket

Patch to fix the mistakes/schema errors in defaultpresets.xml

In 6328/josm:

see #9229 - Mistakes in the defaultpresets.xml (modified patch by DeeHants)

Thanks for the patch, could you please attach another one for the other issue you mentioned ?

I've had another look and the zh-hant and zh-hans are both valid, but I don't know the internals of JOSM and its preset localisation.
Some of the local codes use xx_YY while the new ones have been added as zh-XXXX.
Maybe someone that knows it better can suggest the correct corrections to make :)
