DTD for xsp-config files
To get autocompletion in the DDE while editing a xsp-config files,copy the next line into your xsp-config file and alter the path to your repo-folder.
You also get a brief information about the elements and a link to the IBM documentation.
I got the first version of the xsp-config from here: http://stackoverflow.com/questions/17489421/is-there-a-dtd-available-for-xsp-config-file/17511347#17511347
