this is a fix of the NSW detector description
.xml file to avoid an error when the xml ExpressionEvaluator is parsing the file during the layout creation. Thanks to @dellacqu I could easily find the 3 occurences of a doube
;; which cause the ExpressionEvaluator to fail. With this fix, we ensure that the affected code blocks in xml are correctly parsed and interpreted.
Adding also @sroe who might be interested in this
