The standard html entries are presented as strings on the page. However, their values could be bound to other types of objects and primitives. These could be numeric, date or other types. The conversion type specification allows for the designation of such types. The dWebSpec standard types are listed below:

• string (default)
• byte
• short
• integer
• long
• float
• double
• date
• collections

The standard types would ensure platform independence. However, if such independence is not needed, or else as specification matures, platform specific or custom types could or should be included.

On some platform, it could imply some type conversion class; this would have methods to do validations and conversion. For ASP.NET this does not lead to the specification of conversion class.

Without conversion class, it is usual to employ string conversion to the attribute type in the model. To avoid runtime errors it might be necessary to use validation specification to enforce compatibility of the string entered with the bound attribute type in the model.

The standard dWebSpec types and their ASP.NET equivalents are shown in the table below.
