It should be similar in style to UCR - plain English followed by the PS

The document should be structured like BLD --

1. An overview (I like having an example, but I note that BLD does not 
have one (yet)).  Note that a document can have a forward reference from 
an example using PS in the overview to a following section that fully 
defines it.

2. Presentation Syntax
  2.5 EBNF of PS

3. Semantics

4. XML Serialization

etc.

I have no idea why we need more than one example in the introduction, 
and would not include "wish list" features like user-defined externals 
for which we are lacking a robust solution at the moment.

Yes, that is what UCR does (and I urge the BLD editors to consider 
adding a simple example to the BLD overview)

Then use a simpler example.  It doesn't seem to be heavy for UCR.

Yes.

I think we should avoid this in an introductory example, because I have 
doubts that we can or should define
user-defined externals (and isn't this a DTB issue anyway?)

It could be _Gold in the PS

+1 for plain English
