[ka-Map-users] XMLoverlay label

[chunrima]

Hi Maxime, 

I tried to replace 'Info' by xml_overlay in kaXmlOverlay.js.
It seems to work, but the caption show [object Object]. 

I also tried to replace 'info' by xml_overlay.kaMap.geoToPix( this.cxmax,
this.cymin ) in kaXmlOverlay.js for test purposes.
The caption, however, show NaN, NaN. 

My point is that we can resolve this issue if we identify what javascript
objective points to the label attribute in the XML file. 

A better idea? 

Thanks, 

Jae
