The ParameterSize can be use to check the length of a String value. If a min attribute is listed a minMsg will be sent back in an Exception if the String is less than the min length. If a max attribute is listed a maxMsg will be sent back in an Exception if the String is beyond the max length. Here is an example:

<dxp:ParameterSize name="company" min="3" max="40">
   <dxp:Cp name="minMsg">Company must be min of 3 chars in length</dxp:Cp>
   <dxp:Cp name="maxMsg">Company chars beyond 40 will be tuncated</dxp:Cp>
</dxp:ParameterSize>
