[Qgis-developer] QtXml is no longer maintained in Qt5

[Matthias Kuhn]

Hi Marco,

I didn't look at it in detail and just based this recommendation on the
one from the QtXml documentation linked at the end of the original message.
Is there something in particular you think we will be missing? If so, it
might be good to start looking for alternative ways to go.

Regards,
Matthias
