[ka-Map-users] Hilite query

Thank you very much Kwok Lun,
I'm pleased to know somebody is using hilite system and put his hands on.
Not me or Andrea have ever heard of somebody using it.

right
:-)
the external use of SLD should avoid to put hands in the code.
I've already used it in the Embrio prototype and it's cool to me.
it's few lines of code to include it. I just need that while that I've 
not at the moment...

We've decided to avoid vector drawings with XMLOverlay to be safe from 
any memory limit as vector drawing on the browser could be very sensible 
about total amount of vertex loaded.
When you use a ka-Map layer  drawn on the fly you don't care that much 
on how many vertex will be displayed.
