Re:  HTML5 and almost no namespaces
I think the HTML argument is that the context supplies (or implies) the 
namespace.  For example, you'd typically have documents like:

    <name>ABC corp</name>

    <name>Jill Doe</name>

Or even:

        <name>ABC corp</name>

        <name>Jill Doe</name>

By this argument 'name' is not ambiguous because of its context.  In fact 
its quite easy to define a schema that has multiple 'name' elements with 
different meanings.  I believe some would say that is bad design though.

With due respects to people who dislike XML namespaces,

Consider the following example:

The element "name" here represents an organization name.

<name xmlns="http://organization-ns">ABC corp</name>

The element "name" here represents a person name.

<name xmlns="http://person-ns">Jill Doe</name>

If I'm presented with either (or both) of these documents, the
namespace binding helps me (and my XML application) to make a logical
association between the XML markup and to the domain with which it is
related to.

And we all say that, XML namespaces helps us to avoid name collisions
(one of the example of this is given above).

I (therefore) personally like XML namespaces. It's an optional
feature. If someone doesn't need XML namespaces in an application, the
XML software stack allows implementing such a design decision.
