That doesn't seem to make sense to me since you have to escape the
character used for escaping. Otherwise encoding and decoding would not
be reversible, e.g.
(I've added some spaces just in case your client sees these as HTML...)
Encoding: & quot ;
would give: & quot ;
but decoding this would incorrectly give "
Hence this input needs to be encoded as: & amp ; quot ;
to give the correct decoded output: & quot ;
There are plenty of examples in planet.osm of & amp ; being used:
<tag k="name" v="Library & amp ; Community Centre" />
<tag k="name" v="The Waggon & amp ; Horses" />
