The <fo:multi-switch> object holds one or more <fo:multi-case> objects and controls the switching between them (activated by <fo:multi-toggle>)
This object can be used for interactive tasks such as table-of-content views and next/previous views.
The children of this object are one or more <fo:multi-case> objects. However, only one <fo:multi-case> can be visible at a single time. Each <fo:multi-case> object may contain one or more <fo:multi-toggle> objects, which controls the <fo:multi-case> switching of the <fo:multi-switch>.
