That's OK. I can create the type classes myself.
class ToElement a where
toElement :: a -> Element
class FromElement a where
parseElement :: Element -> Either String a
The important thing is that namespaces are understood so that I am able
create instances that compose, e.g. (off the top of my head)
data SoapEnvelope h b = SoapEnvelope
{
soapEnvelopeHeaders :: [h],
soapEnvelopeBody :: b
}
instance (FromElement h, FromElement b) => FromElement (SoapEnvelope h b)
where
parseElement e = SoapEnvelope <$> (...headers...) <*> (...body...)
Thanks,
