16  @todo 1
17 
18  - All PC types could be defined in service/module xml. (done)
19  -- type, class, directory (done)
20  -- internal links used/implemented?
21  -- styles used/implemented?
22  - application classes need
23  -- page object
24  --- page object should return php5 domdoc (getDom() vs getDomDoc()?)
25  esp. plugins should use this
26  -- remove content element hook, if content is not allowed
27  - PC types could move to components (e.g. blog, login)
28  - Problem: How to modularize xsl?
29  -- read from db?
30  -- xml entries say that xslt code is used -> read file and include in
31  main xslt file
