An X-PIL is a text only version of the original patient information leaflet, which is formatted for use by the visually impaired. X-PILs are created in XML (Extensible Mark-up Language) format. XML is an industry standard computer file format that allows data to be shared between systems and displayed in different ways. This enables screen readers to read the X-PILs; in addition the X-PILs can be converted to Braille, audio CD and large print formats.
