The VSPX form controls such as form, button, select-list, text etc. can be rendered as XForms analogues using a special connection variable 'RenderXForms' set to true (integer 1). Also XML post data coming from XForms capable agents will be parsed and provided to the VSPX page methods in usual form (name/value array). The HTML form elements substitution to the XForms is as follows: input type="text" - xforms:input; input type="password" - xforms:secret; textarea - xforms:textarea; select - xforms:select1; select multiple - xforms:select; checkbox - xforms:input (of datatype boolean); input type="radio" - xforms:select1 appearance="full"; input type="submit" - xforms:submit; form - xforms:model. Furthermore validators which belongs to a input elements (not to a containers) will enforce XMLSchema types of the XForms model. Note that some XForms agents may need special object registering or a special Content-Type reported, so as this varies from agent to agent the application logic is responsible for setting them properly.
