Then i wait can be understood i have not time for replying some irrelevant

This sound "no" may kill any debate. I just wonder that others do not

Difficult to see that "easiness" in the model you typed. This may be dut
to my lack of skill. Still the situation is poor, because i do not
understand why liminal, for example, ignores the way you propose.

Moreover, i find amazing that when minimal-simple XML was proposed, many
folks rejected the absence of attribute model for metadata. For instance,
Tim Bray wrote about metadata

<blockquote>
XML Has Both Elements and Attributes, Why?  When I first learned about
SGML, XML's predecessor (this would be in 1987) I had the same reaction,
and single-handedly coerced the markup of the Oxford English Dictionary
online text into an attribute-free style that lasted some years.

Today I observe empirically that people who write markup languages like
having elements and attributes, and I feel nervous about telling people
what they should and shouldn't like. Also, I have one argument by example
that I think is incredibly powerful, a show-stopper:

<a href="http://www.w3.org/";>the W3C</a>

This just seems like an elegantly simple and expressive way to encode an
anchored one-way hyperlink, and I would resent any syntax that forced me
to write it differently.
</blockquote>

Maybe he is unaware of your proposal

 <a id="123">the W3C</a>

 <href idref="123">http://www.w3.org/</href>

This class of double attitude one often find in the XML community is
really perplexing. Is this politics or some kind of non-standard logic is
thougt in academia and i unknow?
