Description
I propose to add an introspection function to get the schema id of a child given its name.
Here is some background for this request. I try to write a GSettingsBackend for my company settings system. But it needs to know all the settings at init, so I introspect settings schemas and to handle children properly I need to retrieve their associated schema id.
