Dear Adhemar,

Thank you for your comments.

We maintain our official Rejection of your request.  Here is our response:

>>> Upon consideration it has become even clearer to us that mark labels
>>> should not even be xsd:id's.  As an example, the uniqueness constraints
>>> of ID's are a hindrance rather than a benefit, e.g. it may well be
>>> desirable to repeatedly use the same mark label (equivalent to repeatedly
>>> sending back the same event).  We also wish to permit integer labels, for

>>> 
>>> Because of this desire to have fewer restrictions than those introduced
>>> by ID's, we have decided to change the name attribute to be of type
>>> xsd:token.

If you believe we have not adequately addressed your request,
please let us know as soon as possible.  If we do not hear
from you within 7 days, we will take this as tacit acceptance.

Again, thank you for your input.

Hello,

Thanks for your official response.

If I understand this correctly, you use the "name" attribute forconveying
information back, because ideally one wants a lot of id's (in various
tags) for external references, but one doesnt want to stream back an
event for every id one encounters, because it isn't necessary. I can
understand that.

But I don't understand why one can't stream back an event for every id
(instead of every name) one encounters in a <mark> tag. This way, every
internal reference can automatically be used as an external reference,
and one doesn't stream back unnecessary events.

(As for "name" being a better description: in the old HTML, external
references were made via <a name="ref"> because name was a better
description of what the attribute was. This is changed in the newer XHTML,
for (informally speaking) complying with XML custom.)

Adhemar.
