ContentTypeAccessController is a hierarchical access controller. Indeed, a content type could inherit from another.
For example:

• Article (article)
  • Actualité (news)
    • Actualité géolocalisée (geo-news)

The rights on content types are stored in JDBC database with contexts such as :

• /content-types/article
• /content-types/article/news
• /content-types/article/news/geo-news

To check rights on a content type of type "geo-news", 4 SQL queries will potentially be done :
1) with context "/content-types/article/news/geo-news"
2) then if not found with "/content-types/article/news"
3) then if not found with "/content-types/article"
4) then if not found with "/content-types"

You could execute only one SQL queryto get all contexts starting with "/content-types", and handle a cache.

Should JdbcProfileAssignmentStorage handle hierarchical context ? Or write a HierarchicalJdbcProfileAssignmentStorage ?
