The example in Reference Guide that shows how to programmatically define node types (http://jboss.org/file-access/default/members/dna/freezone/docs/0.5/manuals/reference/html_single/reference-guide-en.html#d0e6301) has several typos:

1) Change NodeTypeManager on line 2 to JcrNodeTypeManager
2) Change childNode.setRequiredPrimaryTypeNames(...) to childNode.setRequiredPrimaryTypes(...)
3) Add a boolean argument in the method call in the last line.

Also, the text in this section could be more clear about the in which package the DNA-specific interfaces exist.
