action type="xquery" does not work

Excuse me, whenever I use the tag <xapp:action type=“xquery” …?
An error is shown as below.

Here are the tool versions:
Tomcat 4.1.31 (As noted in the previous post, I’ve downgraded it to Xerces 2.1.0)
X-application 4.1.1
Tamino 3.1.1.4

I wonder if it is the problem of the action type “xquery”, because if I change it to “query”, it works. Can anyone help?

Something more. I tried to change it to <xapp:action type=“query” …>
so as to make the action invoked.
However, I can’t display a result by using the tag <xapp:display select="/BasicLaw/Chapter/@id"/>
In the page, it shows ?undefined node : /BasicLaw/Chapter/@id?

I’ve tried the query “/BasicLaw/Chapter/@id” on Tamino Interactive Interface, it works. So I am quite sure that the query is not problematic.

Can anyone help pls? Thanks!
