It's an improvement, thanks; I think it's a bit long, but clearly this
is up to your editorial discretion :)

How do they react when an element in an InkML file as an id of
"DefaultCanvas"?

In any case, even if the spec isn't changed (which seems sub-optimal to
me), I strongly recommend calling out explicitly the restriction on the
authorized ids. It probably ought to be added to the XML Schema as well
if that's technically possible.

That's not what the XML Schema enforces:
   <xsd:element name="ink" type="inkml:ink.type">
      <xsd:key name="channelNameKey">
         <xsd:selector xpath=".//inkml:channel"/>
         <xsd:field xpath="@name"/>
      </xsd:key>
says that no channel can have the same name anywhere in an InkML
document.

HTH,
