Validator: Using "<" and ">" in a mask

[Niebert, Tanja]

Hi,

I want to create a mask validation where I allow alphanumeric characters plus the "<" 
and ">" signs. Using "\<" and "\>" doesn't work. I get an exception saying, that the 
XML-File is not well formed.

This is how my expression looks like:

<var>
     <var-name>mask</var-name>
     <var-value>^[0-9a-zA-Z\<\>]*$</var-value>
</var>

Thanks for your help

Tanja
