New In Version 4.0: XMod Constants are available in templates beginning in version 4. Since constants were originally designed for use in XMod forms, there are a couple of constants that don't make sense in the context of templates. Specifically, you should use the template tag <xmod:recordid/> instead of {XMOD_XModIdBefore} and {XMOD_XModIdAfter}.
Constants may be placed in detail and list view templates. Additionally, you can place them in the header and footer areas of your list view templates.
For more information on XMod Constants, please refer to the help topic under the Form Controls section.
