## Description

A "schema" describes a key-value pair in a MateConf database. It may include information such as default value and value type, as well as documentation describing the pair, the name of the application that created the pair, etc.

A MateConfSchema duplicates some of the information about the value it describes, such as type information. In these cases, the type information provided describes what the type of the value should be, not what the type actually is.

## Details

### MateConfSchema

    typedef struct _MateConfSchema MateConfSchema;

An opaque data type representing a description of a key-value pair.
