Hi,

I am trying to draw ArcInfo annotation via OGR, using MapServer v3.6.1 
(windows binary) on Windows NT.
I cannot get MapServer to draw the actual annotation text.  Is this 
possible, have i got a syntax error somewhere.

regards
/Matthew

Extract from arc DESCRIBE command on cover:

                 Description of DOUBLE precision coverage anno15b

                                 FEATURE CLASSES

                                     Number of  Attribute     Spatial
Feature Class          Subclass     Features   data (bytes)  Index?
-------------          --------     ---------  ------------  -------
ANNOTATIONS                 SDE          2188       524      Yes

Extract from arc ITEMS anno15b.tatsde command on cover:

   ITEM NAME        WIDTH OUTPUT  TYPE
SDE#                   4     5     B
SDE-ID                 4     5     B
OBJECT_ID              4    10     B
ANNOTYPE              30    30     C
NAME                 250   250     C

---------------------------------------------------------
Using the following syntax with TYPE=Point:

LAYER
   NAME anno15
   TYPE POINT
   CONNECTIONTYPE OGR
   CONNECTION "C:\apache\htdocs\gt2\data\anno15b,0"
   STATUS default
   CLASS
     COLOR 0 0 0
   END
END

Mapserver draws points at the start of where each annotation string should be.

---------------------------------------------------------
Using the following syntax with TYPE=Annotation:

LAYER
   NAME anno15
   TYPE ANNOTATION
   CONNECTIONTYPE OGR
   CONNECTION "C:\apache\htdocs\gt2\data\anno15b,0"
   STATUS default
   CLASS
     COLOR 0 0 0
   END
END

Mapserver draws nothing for this layer, but gives no error either.  The 
rest of the layers still draw.

---------------------------------------------------------
Using the following syntax with TYPE=Annotation and with a TEXT fixed label:

LAYER
   NAME anno15
   TYPE ANNOTATION
   CONNECTIONTYPE OGR
   CONNECTION "C:\apache\htdocs\gt2\data\anno15b,0"
   STATUS default
   CLASS
     COLOR 0 0 0
     TEXT "hello"
     LABEL
       COLOR 0 0 0
     END
   END
END

Mapserver draws the default text where each annotation string should have been.

---------------------------------------------------------
Using the following syntax with TYPE=Annotation and with a LABELITEM:

LAYER
   NAME anno15
   TYPE ANNOTATION
   CONNECTIONTYPE OGR
   CONNECTION "C:\apache\htdocs\gt2\data\anno15b,0"
   STATUS default
   LABELITEM "NAME"
   CLASS
     COLOR 0 0 0
   END
END

MapServer gives the error:
msOGRLayerInitItemInfo(): OGR error. Invalid Field name: NAME
I have tried both NAME,name,Name without success
