Thank you for this clear description Jukka, I will follow Ede's suggestion to log a warning if a (mandatory) title is missing in a layer to let him a chance to report the problem, but the main thing was to make it possible to use the WMS even if it contains such a layer (it will then contain "<name> (untitled)" as its title).

objet : Re: [JPP-Devel] wms layer title
From the WMS 1.3.0 standard:
7.2.4.6.2 Title
A <Title> is mandatory for all layers; it is a human-readable string for presentation in a menu. The Title is not inherited by child Layers.
7.2.4.6.3 Name
If, and only if, a layer has a <Name>, then it is a map layer that can be requested by using that Name in the LAYERS parameter of a GetMap request. A Layer that contains a <Name> element is referred to as a “named layer” in this International Standard. If the layer has a Title but no Name, then that layer is only a category title for all the layers nested within. A server that advertises a Layer containing a Name element shall be able to accept that Name as the value of LAYERS argument in a GetMap request and return the corresponding map. A client
shall not attempt to request a layer that has a Title but no Name.

Aihe: Re: [JPP-Devel] wms layer title
i see. right. that happens when you don't have a proper test dataset :). we should maybe also log a warning as an empty title is irregular as i understand. is it not?

Seems that the getTitle you changed is a global title of the main document.
Anyway, I could have a try this morning with the co-worker who
reported the bug, and the bug was still there.
