/* A schedule (sub)tree.
*
* The leaves of a tree are not explicitly represented inside
- * the isl_schedule_tree. If a tree consists of only a leaf,
- * then it is equal to the static object isl_schedule_tree_empty.
- *
- * ctx may be NULL if type is isl_schedule_node_leaf.
- * In this case, ref has a negative value.
+ * the isl_schedule_tree, except when the tree consists of only a leaf.
*
* The "band" field is valid when type is isl_schedule_node_band.
+ * The "context" field is valid when type is isl_schedule_node_context
+ * and represents constraints on the flat product of the outer band nodes,
+ * possibly introducing additional parameters.
* The "domain" field is valid when type is isl_schedule_node_domain
* and introduces the statement instances scheduled by the tree.
+ *
+ * The "contraction" and "expansion" fields are valid when type
+ * is isl_schedule_node_expansion.
+ * "expansion" expands the reaching domain elements to one or more
+ * domain elements for the subtree.
+ * "contraction" maps these elements back to the corresponding
+ * reaching domain element. It does not involve any domain constraints.
+ *
+ * The "extension" field is valid when the is isl_schedule_node_extension
+ * maps outer schedule dimensions (the flat product of the outer band nodes)
+ * to additional iteration domains.
+ *
* The "filter" field is valid when type is isl_schedule_node_filter
* and represents the statement instances selected by the node.
*
+ * The "guard" field is valid when type is isl_schedule_node_guard
+ * and represents constraints on the flat product of the outer band nodes
+ * that need to be enforced by the outer nodes in the generated AST.
+ *
+ * The "mark" field is valid when type is isl_schedule_node_mark and
+ * identifies the mark.
+ *
* The "children" field is valid for all types except
* isl_schedule_node_leaf. This field is NULL if there are
* no children (except for the implicit leaves).
+ *
+ * anchored is set if the node or any of its descendants depends
+ * on its position in the schedule tree.
