Related to: #227 and #259

Though the specs allows you to omit the <ele> tag: 👉 https://www.topografix.com/GPX/1/1/#type_wptType

<ele> [xsd](https://www.topografix.com/GPX/1/1/#ns_xsd):decimal </ele> [0..1]

I don't recommend doing so, in terms of software portability as well.. (generally speaking: undefined != 0)

OK: ele = 0
