I understand; I read another thread about that. I deliberately left the
encoders there for testing purposes to help me verify easily that the
source attribute was being released.

OK. Is that the only way of overriding it?

I'm looking at this because I'm trying to understand the implications of
the ComputedIdConnector and StoredIdConnector having been deprecated in
favour of "an equivalent NameID "generator"".

eduPersonTargetedID/urn:oid: is a core UK 
federation attribute, it's used by many UK SPs to key to registration 
data; if we aren't supposed to use ComputedIdConnector or 
StoredIdConnector to generate it then I'm not sure what we should do 
instead. Can we use a NameID generator to generate it and release it as 
an attribute the way we have been doing, or will we have to look at 
moving to a persistent NameID instead?

(I know that ComputedIdConnector still works at present; it's working 
fine for me. I'm trying to understand implications for the future)
