asp.net mvc error handling
i'm a newbie .net mvc developer and i want to know, is there anyway to develop my own error handler without using the famous try/catch statement. i'm using an XML file to render components in a view, and i want for example to get an error message useful for me to know that i violated a constraint based on the xml file 
>(example <var type="textField" required="true" language="fr"> if i add another tag without >'type' attribute, this can generate a message for me at runtime). i hope i make myself clear
thanks in advance,
