- The <code>tile</code> element is a type of feature which is associated with a tiled coordinate reference system that subdivides or 'tiles' 2D space in a recursively repeating grid pattern, where the origin of both the tiled
- coordinate reference system and the grid at all zoom levels is defined in coordinates of an underlying projected coordinate reference system.
- </p>
- <p>
- A defining characteristic of tiled coordinate reference systems is that they rely on integer grid row/col coordinates and zoom values. The use of these values in URLs can yield highly cacheable resources, which can lead to
- high-performance map services.
- </p>
- <p>
- The "zoom" value is a global integer property of a MapML document whose coordinate system is defined by this specification. All MapML documents have a defined zoom value. The "zoom" value is equal to the
- <code>zoom@value</code> child of the <a href="#the-extent-element"><code>extent</code></a> element. Hence the zoom value is not a direct attribute of the <code>tile</code> element.
- </p>
- <p>
- The main example of such a tiled coordinate reference system is <a href="#OSMTILE"><code>OSMTILE</code></a>, although others exist.

+ <p>
+ The <code>tile</code> element is a type of feature which is associated with a tiled coordinate reference system that subdivides or 'tiles' 2D space in a recursively repeating grid pattern, where the origin of both the tiled
+ coordinate reference system and the grid at all zoom levels is defined in coordinates of an underlying projected coordinate reference system.
+ </p>
+ <p>
+ A defining characteristic of tiled coordinate reference systems is that they rely on integer grid row/col coordinates and zoom values. The use of these values in URLs can yield highly cacheable resources, which can lead to
+ high-performance map services.
+ </p>
+ <p>
+ The "zoom" value is a global integer property of a MapML document whose coordinate system is defined by this specification. All MapML documents have a defined zoom value. The "zoom" value is equal to the
+ <code>zoom@value</code> child of the <a href="#the-extent-element"><code>extent</code></a> element. Hence the zoom value is not a direct attribute of the <code>tile</code> element.
+ </p>
+ <p>
+ The main example of such a tiled coordinate reference system is <a href="#OSMTILE"><code>OSMTILE</code></a>, although others exist.
