[Zope] Validating data entry (dates)

[Jens Vagelpohl]

hi henny,

my suggestion for data validation *before* submitting the form would be
javascript. (is that blasphemy??? ;)

DTML is interpreted on the server, so you would not be able to validate
using DTML without sending the data back to the server...
