// to blindly (i.e. wihtout asking the provider) propagate facets from S-Space properties
// to C-Space properties. Providers for other databases may use facets to distinguish among
// different types in which case the mismatch between facets on C-Space properties and S-Space
// properties is intentional and facet propagation breaks this. In general we should always ask
// the provider about the type before we propagate facet values. This is a major change though
// so for now we will limit the default facet propagation to SqlServer and Sql Server CE only.
