STYLED LAYER DESCRIPTOR version 1.0.20 (2002-09-21)
This schema document follows NIEM practice of a single schema document per namespace. It contains the definitions from the OGC schema documents common.xsd, Symbol.xsd, FeatureStyle.xsd, and StyledLayerDescriptor.xsd. See: http://schemas.opengeospatial.net/sld/1.0.20/.
It is an adaptation of the original in that it imports version 1.1 instead of version 1.0 of the filter schema. So the most minor version should be incremented to 21 for change proposal to OGC.
2006-09-28 Changed namespaces and schema locations
ns old http://niem.gov/niem/external/xlink/1.0.0/dhs-gmo/1.0.0
ns new http://niem.gov/niem/external/w3c-xlink/1.0/dhs-gmo/1.0.0
from ../../../../xlink/1.0.0/dhs-gmo/1.0.0/xlinks.xsd
to ../../../../w3c-xlink/1.0/dhs-gmo/1.0.0/xlinks.xsd
2006-09-21 Changes
1. Change namespaces following NIEM conventions
a) targetNamespace http://niem.gov/niem/external/ogc-sld/1.0.20/dhs-gmo/1.0.0
b) ogc namespace http://niem.gov/niem/external/ogc-filter/1.1.0/dhs-gmo/1.1.0
c) xlink namespace http://niem.gov/niem/external/xlink/1.0.0/dhs-gmo/1.0.0
2006-09-04 Changes
1. Change namespaces following conventions proposed in OGC 05-065r3 to include version and profile information,
except that complete version is used instead of BNF "principle version".
a) targetNamespace was http://www.opengis.net/sld; changed to http://www.opengis.net/sld/1.0.20/DHS-GMO/1.0.0
b) ogc namespace was http://www.opengis.net/ogc; changed to http://www.opengis.net/ogc/1.1.0/DHS-GMO/1.0.0
c) xlink namespace was http://www.w3.org/1999/xlink; changed to http://www.w3.org/1999/xlink/1.0.0/OGC-DHS-GMO/1.0.0

The MappedColorSubSymbol identifies the the symbol to which
to apply computed colors. The computed color is used as the
'default color' in the sub-symbol. The "matchTo" attribute tells
whether to match the lookup value to the "quantity" or "label"
attributes of the 'choropleth' ColorMap.

The UseSLDLibrary tag specifies that an external SLD document

augment the set of named layers and styles that are available

SLD library takes precedence over the ones internal to the WMS.
Any number of libraries may be specified in an SLD and each
successive library takes precedence over the former ones in the
case of name collisions.
