Help is stored in ADP files in a subdirectory off of
packages/package-key/www called "help".
Help for each file can be found by looking for filename.adp.
Locale specific help can be found by filename.locale.adp.
Help files should be available from a URL such as
package_url/www/help/filename#form.form-element
The request processor should return the correct locale specific help
file if it is available.
Form specific help can be found by help_url#form
Form element specific help can be found by help_url#form.form-element
