Original Message From: "Micah Dubinko"

A set of "using" declarations could also work like the relatively well- known concept of DNS search domains.

Mentioning DNS gave me food for thought. Here's a proposal that has a hint of DNS and perhaps a hint of e-mail address resolution.

1) fully qualified names should have the form:

local_name:namespace

2) A name without a namespace belongs to the namespace of the elements nearest ancestor that does have a namespace.

3) A name can also be specified using a partial namespace, e.g.:

local_name:partial_namespace

4) Unless a name ends with a . or :, on encountering a (possibly) partial namespace, a search is made to see if an ancestor element has a namespace that starts with that partial namespace. If one is found, the namespace becomes that of the full namespace. For example, if an ancestor element has the name:

myName:proposal.example.com

then a name of:

anotherName:proposal

is treated as:

anotherName:proposal.example.com

If 'proposal' really is the full namespace, and an ancestor has a namespace of 'proposal.example.com' then you can prevent the expansion by doing:

anotherName:proposal.

Trailing .s and :s are obviously removed when selecting the namespace part.

5) For the purposes of HTML5, the HTML5 namespace can be considered to be in-scope prior to the start of parsing so that documents can start simply as:

<html ...

By way of example:

<html> <head> <root:myExtension.example.com> <child> <html:html> <body> <extra:myExtension/> </body> </html:html> </child> </root:myExtension.example.com> </head> ... </html>

- The outer 'html', and 'head' are part of the HTML5 namespace, which is assumed to be something like 'html.w3c.org'.

- The full name of 'child' is 'child:myExtension.example.com'.

- The 'html:html' takes us back to the HTML namespace, and so 'body' is part of the HTML namespace.

- 'extra:myExtension' is treated as 'extra:myExtension.example.com'.

I think this is simple and allows brevity without having to remember a lot of syntax. It puts the burden on the tools rather than on the document authors.
