> The issue reported affects two similar use cases:
> * XML view of JMS subscribers is rendered with syntax errors if any of the subscribers has a selector containing an XML-prohibited character in its statement, e.g. {{PROPERTY <> VALUE}} selector statement contains {{<}} and {{>}} characters that cause XML syntax errors
> * HTML view of JMS subscribers does not properly display the selector statement if it contains any of the XML-prohibited characters in it, e.g. {{PROPERTY <> VALUE}} will be displayed as {{PROPERTY VALUE}} - both the {{<}} and {{>}} characters are stripped out
>  
> The solution is to use the {{<c:out value=""/>}} syntax whenever an XML-unescaped string is to be outputted - the {{c:out}} has the {{escapeXml}} property set to {{true}} by default which does the trick.
> I have attached the patch that fixes the XML escaping for JMS selector. 
> Please note that I could not find any JMS naming specification to make sure whether the JMS selector is the only field that is allowed to contain XML-prohibited characters. Therefore I would advise the patch reviewer to figure  out whether this fix should also be applied to JMS Client ID, Connection ID, Destination Name and Subscription name fields.
