flaw in SLD label implementation

[Eijnden, Bart van den (AGI)]

Hi list,

I am trying to get Mapserver (version 4.8.4) to display labels for a certain attribute column. This works fine if I use the non-conformant OGC request (only part of my SLD):

<TextSymbolizer><Label>MY_COLUMN</Label>

According to the OGC SLD spec Mapserver should just label with MY_COLUMN as a static string.

But it does not work if I use it the way the example in the SLD spec indicates (using ogc:PropertyName):

<TextSymbolizer><Label><ogc:PropertyName>MY_COLUMN</ogc:PropertyName></Label>

I get:
[Thu Aug 10 08:06:30 2006] [error] [client 145.50.39.34] Thu Aug 10 08:06:30 2006 - msDBFGetItemIndex(): DBASE file error. Item 'PropertyName' not found.

Example from SLD spec:
<TextSymbolizer>
<Geometry>
<ogc:PropertyName>locatedAt</ogc:PropertyName>
</Geometry>
<Label>
<ogc:PropertyName>hospitalName</ogc:PropertyName>
</Label>

Why is this important? So that you can label using attribute values and static strings combined, like:
<Label>This is city "<ogc:PropertyName>NAME</ogc:PropertyName>"
of state <ogc:PropertyName>STATE</ogc:PropertyName></Label>

Can this be fixed?

Best regards,
