Malformed WMS GetFeatureInfo XML response if raster sample dimension description not valid NCName

Issue Type:	Bug
Affects Versions:	2.9.1, 2.10-M0
Assignee:	Ben Caradoc-Davies [Administrator]
Components:	NetCDF, WMS
Created:	05/Sep/16 5:02 AM
Priority:	Medium
Reporter:	Ben Caradoc-Davies [Administrator]

RasterLayerIdentifier builds a SimpleFeatureType to service WMS GetFeatureInfo requests by using the sample dimension descriptions as the local names of the properties. For NetCDF, these are the long_name of the source variable, but this attribute can contain any text, including spaces. Because the local name of any XML element must be an xs:NCName, a property name built from a long_name that contains spaces causes a GetFeatureInfo XML response to be malformed. For example, a coverage from a NetCDF file with: analyzed_sst:long_name = "Analyzed Sea Surface Temperature" will result in malformed GetFeatureInfo XML responses like this snippet: <sf:Analyzed Sea Surface Temperature>23.0</sf:Analyzed Sea Surface Temperature> The proposed solution is to convert sample dimension descriptions to valid NCNames by replacing invalid characters with underscore ("_") and null or empty descriptions with Unknown".
