At the very end of the Repos Doclang document, there are a few typos. Repo.boot is listed three times, linking to three separate things.

File: src/doc/docLang/doc/Repos.fandoc

Line: 192

[Repo.boot]`sys::Repo.list`: list of all repos in priority 
  order - working is always first and boot is always last 
[Repo.boot]`sys::Repo.boot`: the boot repo 
[Repo.boot]`sys::Repo.working`: the working repo (may be same as boot) 

fixed

thanks for reporting
