So far, we have modeled the PTAEO input as a single box with dots separating the values for the fields.
The next phase is to submit the PTAEO to the webmethods PTAEO validator.
Next we need to either silently accept the value, or perhaps provide a visual cue that the value is accepted. Perhaps turn the field green.
If the the value is bad, we need to provide some form of notification of the mistake. This functionality is already built-into the webmethods WSDL; it's passed along as a text error message. The simplest notification would be a popup with the content of the WSDL complaint passed-through. Nicer would be some color or syntax highlighting.
