Blocking free javascript

[Julien Lepiller]

Hi,

My page at https://i18n.lepiller.eu/i18n.html shows some data related to i18n. 
To get historical or per-locale data, I have written a short script that 
creates a menu and lets you select a date or a locale. I have licensed it under 
the Expat licence.

As you can see from the source code, I tried to have it recognised properly by 
librejs, but it's still blocked with the explanation being "script uses a 
reserved object (XMLHttpRequest)". What I have tried is to add a script with 
only the licensed, with @licstart and @licend, as described in the 
documentation. That didn't work, so I tried to wrap the blocked script between 
@license and @end-license, but that didn't work either. What did I do wrong?

Thanks in advance for any help you can provide (please keep me in CC)!
