+# Pointer templates
+
+This format provides the concept of **pointer templates** to allow
+deduplicating representations. Pointer templates are defined to specify the
+variables they expect in scope and the pointer definition that uses those
+variables.
+
+## Template schema {#template-schema}
+
+The following schema defines how to represent a single pointer template.
+See [below](#templates-schema) for how to organize pointer templates by name.

+## Organizing templates {#templates-schema}

+a collection of pointer templates by name.
