That was a thread on the use of signing elements in <Link> elements.<br>
<br>
Dirk's use of <Host> in his example XRD is not valid XRD syntax.<br>
<br>
It wasn't commented on because it was not the topic of the email thread.<br>

Hi John,<br>
The last time I saw an example of an XRD host-meta is here on 15th Oct here<br>
<a href="http://lists.oasis-open.org/archives/xri/200910/msg00055.html" target="_blank">http://lists.oasis-open.org/archives/xri/200910/msg00055.html</a><br>
<br>
It has a <Host> instead of <Subject>. If you are saying that it is not part<br>
of the XRD spec and it is part of the host-meta spec, it still doesnt change<br>
my argument. As an end-user of the the discovery mechanism the effect is<br>
still the same for me.<br>
<br>
You say you have a hard time following me! Isn't it a case of the pot<br>
calling the kettle black? How many people are going to follow what you have<br>
said bellow. I will only quote one sentence you have written and ignore the<br>
rest.<div class="im"><br>
<br>
"The Subject of a XRD is the <Subject> of the XRD there can be 0 or 1<br>
in an XRD."<br>
<br></div>
That is exactly what you said. Now tell me how can there be a "0" <Subject><br>
for an XRD. What meaning does an XRD have with "0" <Subject>?<div><div></div><div class="h5"><br>

Hi Santosh,<br>
<br>
I am having a hard time following your point.<br>
<br>
This is the current draft of the XRD spec.<br>
<a href="http://www.oasis-open.org/committees/download.php/34724/xrd-1.0-wd09.html" target="_blank">http://www.oasis-open.org/committees/download.php/34724/xrd-1.0-wd09.html</a><br>
<br>
There is no <Host> element in the spec.<br>
<br>
The Subject of a XRD is the <Subject> of the XRD there can be 0 or 1<br>
in an XRD.<br>
<br>
HostMeta is a spec that uses the OASIS XRD spec.<br>
<br>
I know that they want to have what is essentially an abstract Subject.<br>
<br>
ie one that is about the host and not the URI.<br>
<br>
This is a URL problem and not an XRI one.<br>
<br>
Any number of wars have been fought over how to represent non-<br>
information resources with URI.<br>
<br>
We did give the group working on host-meta as a itef spec some options<br>
on how they might do that.<br>
<br>
Using the DNS scheme or a URI fragment are all possibilities. I don't<br>
know if they have come to a conclusion. Whatever they decide someone<br>
will be unhappy if history is anything to go by on this topic.<br>
<br>
There is a public review period for XRD coming up and a process for<br>
you to make formal submissions if you want to have input but not join<br>
the TC.<br>

This is an Open Challenge i am sending to the webfinger, XRD forums.<br>
These<br>
guys really think I am an Idiot. "Maybe I am". "BUT I AM NOT GOING<br>
DOWN<br>
WITHOUT A FIGHT".<br>
<br>
Really, I really don't know. Let us hear the arguments they give.<br>
Maybe i am<br>
a brainless stupid, that is why i feel all of them are hollow. But<br>
let them<br>
prove I am stupid. "IF THEY CAN", IF they can, we will hand it to<br>
them, "THE<br>
IDENTITY OSCAR".<br>
<br>
<br>
<br>
Hi All,I know you guys don't like to hear from me. I have been told<br>
so much.<br>
By your moderators. That people on this forum are not "Happy" to<br>
hear from<br>
me.<br>
Like it or "NOT" you are going to hear from me. I am not sure if<br>
this post<br>
of mine will be allowed to be published. But let us see.<br>
I have so many grouses with "XRD" and today I am going to start with<br>
my<br>
first grouse. Since WebFinger by definition is going to follow XRD,<br>
don't<br>
argue with me about webfinger. Lets talk about XRD to start with me.<br>
I am throwing a challenge to all the XRD guys. Prove to me that the<br>
<Subject> of an XRD host-meta document has to be <Host> instead of<br>
<Subject>. If you "smart" guys can prove this to me, I will agree<br>
that "I am<br>
a complete Idiot". If "NOT" all of you web fingerer's and XRD's are<br>
Idiots!!!!<br>
