OK. Here is my solution. I opened the xhtml5.xsd file and defined a new 
complex element type called 'elementContentElement':

     <xs:complexType mixed="false" name="elementContentElement">
         <xs:sequence maxOccurs="unbounded" minOccurs="0">
             <xs:group ref="flowContent"></xs:group>
         </xs:sequence>
         <xs:attributeGroup ref="globalAttributes"></xs:attributeGroup>
     </xs:complexType>

(The 'elementConentType' is identical to the 'flowContentElement' except 
for the @mixed attribute which is set to "false".)

Then I changed @base attribute of the xs:extension element inside the 
setup for the body element (and on some other elements of similar XSD 
construct - they are at least the <slot> and the <blockquote> element):

     <xs:element name="body">
         <xs:complexType>
             <xs:complexContent>
                 <xs:extension base="elementContentElement">
                     <xs:attributeGroup 
ref="bodyEventHandlerAttributes"></xs:attributeGroup>
                 </xs:extension>
             </xs:complexContent>
         </xs:complexType>
     </xs:element>

Finally I changed the sectioning content elements to the new (but 
traditional ...) element type:

     <xs:element name="article" type="elementContentElement"/>
     <xs:element name="section" type="elementContentElement"/>
     <xs:element name="nav" type="elementContentElement"/>
     <xs:element name="aside" type="elementContentElement"/>

Of course, I could have limited myself to changing <body> and the 
sectioning contents elements. However, I made the above changes to 
<blockquote>, <main>, <form>, <header>, <footer>, <dd>, <li>, <main>, 
<map>, <dialog>, <slot> and <canvas>. But for now, I did not change the 
elements <li>, <dd> and <div>.

Finally I have 2 questions:

1) How could I make the changes into a customization, rather than 
alterning the original XSD?

2) How can I program XXE to defualt to include a <p> child when I add a 
new <li> and <dd> elements?
