 ### schema v5.3.0
 * General Requirements
 * Required Ontologies
-* uns (Dataset metadata)
+
+* X (Matrix Layers)
+  * Updated _Visium Spatial Gene Expression_ table row to _Descendants of Visium Spatial Gene Expression_
+  * Added matrix requirements for _Visium CytAssist Spatial Gene Expression, 11mm_.
+* obs (Cell metadata)
+  * Updated  the requirements for `array_col`:
+    *  MUST be annotated if the `assay_ontology_term_id` is a descendant of _Visium Spatial Gene Expression_
+    * Added ranges for _Visium CytAssist Spatial Gene Expression, 6.5mm_ and _Visium CytAssist Spatial Gene Expression, 11mm_ 
+  * Updated the requirements for `array_row`:
