If you count the requirements expressed in English as a "schema", yes.

The implied schema for the fix-ups is roughly HTML 4.01 Transitional,  
because the fix-ups are based on browser behavior and browser  
behavior has been influenced by HTML 4.01 Transitional. The English  
"schema" for the higher-level HTML5 syntax is separate from the  
parser fix-ups. There is a non-normative RELAX NG plus Schematron  
schema in the works for the higher-level syntax.
