I have a folder call tabledef which use dtmldocument to keep some field
definition like its label, size, default value, help text etc. Which I would
like to generate the data entry form for it. The data will be stored as
object properties, so If I generate a edit form, then I should get the
property, lookup the field information in tabledef folder, and get the
label, size, information from there.
