## Detailed Description

Extended plug-in interface IEditController for a component: Vst::IXmlRepresentationController.

- [plug imp]
- [extends IEditController]
- [released: 3.5.0]
- [optional]

A representation based on XML is a way to export, structure, and group plug-ins parameters for a specific remote (hardware or software rack (such as quick controls)).
It allows to describe each parameter more precisely (what is the best matching to a knob, different title lengths matching limited remote display,...).
See an Example.

- A representation is composed of pages (this means that to see all exported parameters, the user has to navigate through the pages).
- A page is composed of cells (for example 8 cells per page).
- A cell is composed of layers (for example a cell could have a knob, a display, and a button, which means 3 layers).
- A layer is associated to a plug-in parameter using the ParameterID as identifier:
  - it could be a knob with a display for title and/or value, this display uses the same parameterId, but it could an another one.
  - switch
  - link which allows to jump directly to a subpage (another page)
  - more... See Vst::LayerType

This representation is implemented as XML text following the Document Type Definition (DTD): http://dtd.steinberg.net/VST-Remote-1.1.dtd

# Example

Here an example of what should be passed in the stream of getXmlRepresentationStream:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE vstXML PUBLIC "-//Steinberg//DTD VST Remote 1.1//EN" "http://dtd.steinberg.net/VST-Remote-1.1.dtd">
