keyless weather backend: met.no

[yrps]

Like weathercom, and unlike many others, no API key is required for ordinary use. (I question whether requiring an API key is even acceptable for an end-user weather application.)

This is the service that provides data to the xfce4 weather plugin. From the README of that project:

MET.NO API DOCUMENTATION
==========================================================================
To get a quick overview, please consolidate the met.no API weather
documentation and especially their FAQ, which answers some questions
left open by the former:

* General documentation and data licensing
  http://api.yr.no/weatherapi/documentation
  http://api.yr.no/faq.html
  http://api.met.no/license_data.html

* Service-specific documentation
  http://api.met.no/weatherapi/locationforecastlts/1.2/documentation
  http://api.yr.no/weatherapi/sunrise/1.0/documentation

For more technical details you might need to study the XML schema
corresponding to the document in question.

Weather Underground has discontinued its API and I've rewritten the module such that it does not require an API key to use.

I took a look at this API, but it seems to me that it is lacking in several areas. It does not give current conditions (only hour-by-hour forecasts), it does not provide city names, it does not provide visibility, etc.
