[Zope3-dev] local-utility location and registration

[Garanin Michael]

Hello!
My app setup code do follow step:
1) create simple AppSite (as ISite) in top
2) create local-utility object, 
for example PAU = PluggableAuthentication()
3) AppSite['PAU'] = PAU 
4) registration the PAU in AppSite/++etc++site/default.

In other words: local-utility object location in top/mysite, but
registration in top/mysite/++etc++site/default.
Q: It's work, but is it legal?
Thanks!
