-== Taxonomy for loads and stores
+=== Taxonomy for loads and stores
 
 `Zimte` introduces new type of loads and stores to the hart and enforces tag
 checks on certain loads and stores. Following terminologies are defined for
 better clarity and will be used in the rest of the specification.
 
-=== Regular load and regular store operations
+==== Regular load and regular store operations
 Load and store operating on a page with permissions `--R`, `X-R`, `-WR` and
 `XWR` are termed as a `regular load` and `regular store`. Regular load and
 regular store memory operations are generated from an instruction (except
 `settag`) defined by ISA to perform memory accesses.
 
-=== Checked load and store
+==== Checked load and store
 Regular load and store which is subject to tag check is termed as checked load
 and store (or checked memory access)
 
-=== Unchecked load and store
+==== Unchecked load and store
 Regular load and store which is not subject to tag check is termed as unchecked
 load and store (unchecked memory access).

 `load tag` operation is a load of tag from tag storage as defined by Svatag or
 Smvatag extensions. `store tag` operation is a store of tag to tag storage as
 defined by Svatag or Smvatag extensions. `load tag` operation requires
