Thanks for the info.  I've looked at the DTDs, and you are correct. 
GetLegendGraphic and GetStyles are NOT supported as XML elements in 1.1.0 (see
DTD at: http://schemas.opengeospatial.net/wms/1.1.0/capabilities_1_1_0.dtd).  If
I eliminate GetLegendGraphic and GetStyles elements, the XML is valid again. 
We'll have to omit this from the 1.1.0 output Capabilities response.

Keep in mind that, although we will now omit GetLegendGraphic from MapServer's
OGC:WMS 1.1.0 GetCapabilities response, we should still keep the LegendURL in
the capabilities, which points to GetLegendGraphic requests; this is fine (just
because it's not supported in Capabilities XML doesn't mean we can't use it to
offer up a legend image).

Fixed. GetLegendGraphic and GetStyles only appear in 1.1.1 and higher responses.
