condition in xml schema

[21128]

Below is my XML Schema to pass parameter for Crystal Report.
I am wondering if i could give a condition to change Texts inside the <Prompt> </Prompt>. In my case if {?Log_ID}=33 then <Prompt>Include Unit 1 [ Default : Yes ]</Prompt> but if {?Log_ID}=41then <Prompt>Unit Not in this Section</Prompt>
