 Replying to [comment:2 alexvorn2]:
 > I think It should validate only for lower case http not HtTp

 It's completely case-insensitive, so both of those are equivalent, but the
 canonical form should always be 'http'.

 (From memory, there may be further code in `SimplePie_IRI` that can be
 ripped out for this, but that's fairly heavy.)
