I don't think it's using RELAX NG at all. When I run xsltproc on the following 
XML file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML 5.0b1//EN" 
"http://www.oasis-open.org/docbook/xml/5.0b1/dtd/docbook.dtd";>
<book>
  <title>Simple Book</title>
  <chapter>
    <title>Simple Chapter</title>
    <para>Simple Paragraph.</para>
  </chapter>
</book>

it seems to be reading directly from the URL.  But it produces the error I 
posted.  If I repace the DOCTYPE with

<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML 4.5//EN" 
"http://www.oasis-open.org/docbook/xml/4.5CR1/docbookx.dtd";>

It processes successfully.  The Saxon8.6 with xsl2 is producing other errors

Indeed, that cuts both ways. :(

The problem is with MathML, the namespace stuff becomes a big issue.  I don't 
believe RELAX NG solves that unless the XSLT processor can work with 
something other than DTDs.

I have one from www.mathweb.org, but I'm not sure what it would take to get it 
working with DocBook V5.  For that matter, I'm not sure what it would take to 
get /anything/ other than nXML working with DocBook V5 at the moment.

What's the deal with not having MathML in DocBook V5?  If that isn't 
available, I have very little use for DocBook in terms of authoring 
mathematical text.  I'm sure there are ways to persuade DocBook to work with 
MathML even if it is not part of the specification.  Of course that means 
learning yet more about the details of DocBook and the associated tools.  
Perhaps the thing to do is to fork a MathDoc project off of DocBook 
Simplified.  I'm sure me and the other person on the planet who's interested 
in such a product could probably get something working.  BTW, do you happen 
to know that other person's name.  I could use some help!
