Selector Table¶
Before implementing a handler for a certain selector, make sure that it is really necessary for your importer. Many selectors are optional, and only useful for certain special needs.
The Synth column indicates whether or not the selector is applicable to synthetic importers. Custom importers can respond to any of the selectors.
