Nuxeo 5.6 template files, including server.xml.nxftl, appear to use Freemarker interpolations in ways that violate the warning below extracted from this Freemarker document. If you agree, should I open a JIRA for this issue?

Warning!

A frequent mistake of users is the usage of interpolations in places where it shouldn't/can't
be used. Interpolations work only in text sections (e.g. <h1>Hello ${name}!</h1>) and in
string literals (e.g. <#include "/footer/${company}.html">). A typical bad usage is 
<#if ${isBig}>Wow!</#if>, which is syntactically WRONG. You should simply write 
<#if isBig>Wow!</#if>. Also, <#if "${isBig}">Wow!</#if> is WRONG too, since the parameter
value will be a string, and the if directive wants a boolean value, so it will cause a 
runtime error.
