Fixed, thanks.

It means that a MicroXML document which makes proper use of HTML5
elements and attributes will be valid HTML5.  Unfortunately, <br></br>
is interpreted by HTML5 browsers as <br/><br/>, so by making sure always
to use <br/>, the problem can be avoided.

It's in Section 5.4.

One of the main purposes of MicroXML is to avoid the complexity of the
XDM.  Processing instructions don't contain attributes, they just look
as if they do.

There are already specs for MicroXSD and MicroRNG.

I wanted to disallow > in attribute values, but James Clark pointed out
that it is allowed (indeed, required) in Canonical XML documents.  This
means that Canonical XML processors can be used to convert full XML to
MicroXML.  I'm open to the possibility of changing this.

Comments are intentionally as open as possible without losing XML
compatibility.
