RSS feeds need to be validated

[Bios-Marcel]

I couldn't find a go library capable of doing this. The best thing appears to be the one that w3c offers. However, this is sadly written in python and can't be properly integrated into a golang application I assume. I'd rather not want anyone to have to integrate this. Maybe I should write my own validator.

There seems to be a SOAP API for the w3c validator, however, an internet dependency would kind of suck.
