Programmatically access the <compilation /> section of a web.config?

WebConfigurationManager.GetSection("compilation")// Name of the tag in the file
WebConfigurationManager.GetSection("CompilationSection") // Name of the class that I'd expect would be returned by this method
WebConfigurationManager.GetSection("system.web") // Parent tag of the 'compilation' tag

using System.Configuration;
using System.Web.Configuration;

CompilationSection configSection =
          (CompilationSection) ConfigurationManager.GetSection( "system.web/compilation" );

XmlDocument doc = new XmlDocument();
doc.Load(Server.MapPath("~/Web.config"));
doc.SelectSingleNode("/configuration/system.web/compilation/@debug");

CompilationSection section =
    Configuration.GetSection("system.web/compilation") as CompilationSection;
bool debug = section != null && section.Debug;

#if (DEBUG)

#endif
