+          The <a> element
+          must implement, and expose to scripts, the following
+          MathMLAnchorElement interface.

The href getter steps are:

+          
    
+            
  1. Reinitialize url.
    2. 
+            
  2. Let url be this's url.
    3. 
+            
  3. If url is null and this has no [^a/href^] content attribute, then return the empty string.
    4. 
+            
  4. Otherwise, if url is null, then return this's [^a/href^] content attribute's value.
    5. 
+            
  5. Return url, serialized.
    6. 
+          

+

+        

+          
The set the url algorithm for a MathMLAnchorElement are:

+          
    
+            
  1. If this element's [^a/href^] content attribute is absent, then return.
    2. 
+            
  2. Let url be the result of encoding-parsing a URL given this element's [^a/href^] content attribute's value, relative to this element's node document.
    3. 
+            
  3. If url is not failure, then set this's url to url.
    4. 
+          

+        

+
+        
To update href for a MathMLAnchorElement, set the element's [^a/href^] content attribute's
+          value to the element's url, serialized.
