設計歷史 IPloneSiteRoot vs ISiteRoot
collective.lineage INavigationRoot IPossibleSite IChildSite Custom Logo
安裝 0.6 以上版本時，就不需要指定 zcml 設定值，安裝 1.1 以上版本時，必須搭配 Plone 4.1 以上的版本。
如何指定 IPloneSiteRoot 給 Child Site: 透過 ZMI 的 Interfaces 管理頁籤，或是透過 collective.interfaces 模組提供管理介面。
For Plone 5 and collective.lineage with lineage.registry, we're much better off - since all configuration settings are stored in the registry it is possible to configure each IChildSite individually, if lineage.registry is in place.
Here is an example of storing a site logo in the registry for Plone 4.3: https://github.com/collective/collective.sitelogo/blob/master/src/collective/sitelogo/configure.zcml#L41
