TextSymbolizer gets lost with generateSLD

[guillaume]

Not really a bug, but not a feature either... When you generate a map piece with applySLD, if there is a TextSymbolizer it is translated into a TEXT "[theField]" part of the CLASS block. When you want your SLD back from the mapfile, generateSLD only looks into LABELITEM at LAYER's level. So you lose your TextSymbolizer in the returned SLD. I did a quick and dirty fix for my usage I wouldn't dare to show here, but the main idea is : mapogcsld.c, lines 4035sqq : change :

    if (psClass && psLayer && psLayer->labelitem &&
       strlen(psLayer->labelitem) > 0)

to something which tests psClass->text too.
3 lines further, change

    snprintf(szTmp, sizeof(szTmp), "<%sLabel>%s</%sLabel>\n",  sNameSpace,psLayer->labelitem, sNameSpace);

to apply the correct item used to label.
