How-To "IN" a list of items to an XQuery Expression.

Question

Greetings All, I have a query that is working as expected:
SELECT count(*)
FROM XML_TEST
WHERE XMLExists('/ArrayOfCustomField/CustomField/NumberValue\[. >= 12.48 and . <= 321.56\]' PASSING CustomFields);
This provides me with essentially the "BETWEEN" operator.
However, I need to mimic the "IN" operator, e.g.)
SELECT count(*)
FROM XML_TEST
WHERE XMLExists('/ArrayOfCustomField/CustomField/NumberValue\[ IN 12.48, 321.56, 4993.2\]' PASSING CustomFields);
**The query directly above obviously does not work.
With that said how do I reformat the offending query to do what I need it to do?
I am not restricted to using XMLExists and I am open to any type of xml query that will allow me to pass in a string of items to query on.
Any and all help would be greatly appreciated.

The point was only to demonstrate how you'd mimic the IN operator.
I used
  ENAME/text()= ("SCOTT","JAMES")
...which in your case would be sth like
  '/ArrayOfCustomField/CustomField/NumberValue = (12.48, 321.56, 4993.2)'
