7.13 Filter capabilities
The filterCapabilities.xsd schema defines metadata that is used to describe the specific elements that a particular implementation of this International Standard supports. A client application can inspect the filter
capabilities metadata Figures 10 to 17 and be able to determine which operators and types a filter expression processor supports.
The filter capabilities metadata can be embedded in a larger metadata document describing a system of which a filter expression processor is one component. For example a web feature service see ISO 19142 that uses
the XML encoding of a filter expression would include a filter capabilities fragment in its capabilities document to advertize what filter capabilities the service supports.
