Inclusion debates/Rachel Survived, White Canvas, The Gendar Conspiracy, Iris Explains, The School of Doom and more

From Tardis Wiki, the free Doctor Who reference

really do forgive me if this has been covered elsewhere, but i couldn't find it on any of the talkpages. what is the reason that we do not consider these stories to be valid sources? two of them (Iris Explains and The School of Doom) we do not even cover on this site.

it appears to me that each of these releases pass our four little rules with flying colours.

1. each are stories in their own right.

2. all are "licensed by all of the relevant copyright holders".

3. all were officially released.

4. all were intended to feature within the DWU, at least in part.
