Implicit-tiling spec carried by an implicit TileNode, enough to expand its subtree lazily by Morton index during selection (box subdivision for per-tile bounding volumes, templated subtree / content URIs).
Total levels available (root level 0 .. availableLevels-1).
Optional
Content uri template, if the tile has content.
uri
Root tile's local-frame box (12 numbers) subdivided per coordinate.
box
subtrees.uri template ({level}/{x}/{y}/{z}).
subtrees.uri
{level}/{x}/{y}/{z}
