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
