Composite Sources
Composite Sources allows combining multiple sources into one. Composite Source consists of multiple sources separated by
comma {source1},...,{sourceN}
Each source in a composite source can be accessed with its {source_name} as a source-layer property.
Composite source TileJSON endpoint is available
at /{source1},...,{sourceN}, and tiles are available at /{source1},...,{sourceN}/{z}/{x}/{y}.
For example, composite source combining points and lines sources will be available at /points,lines/{z}/{x}/{y}
# TileJSON

# Whole world as a single tile
