Hi all,

At yesterday’s meeting [1] i volunteered to reread the Architecture wiki [2] and the draft
architecture spec [3]. I have a goal of getting the architecture spec into shape so that
we can publish it as a FPWD the first week of April.

To that end, I edited it to make it align more with what is in the wiki. I welcome feedback on the
updated draft [3].

The three main parts of the document are now:

 * An overview of the anticipated user experience. Some of this is covered in the wiki, but in more
   detail than I think we need in the spec.
 * The “components” that emerge from the user experience.
 * The organization of the specifications that together (will) describe interactions among these

I also made it clearer in this draft that the “payment request architecture” is not the only thing
that the WG is developing. To that end, I have also updated the title, now "Payment Request API
Architecture”. The purpose of the spec, therefore, is  narrowly to explain how the associated specifications
(for payment method identifiers, payment request API, etc.) fit together.  It is not a description of
a complete or comprehensive payment architecture for the Web.

The spec still needs work, but I wanted to share this direction with people to see if there is

If we decide to publish this as a FPWD, I would like to then update the Wiki to prune away
some material (and refer instead to the spec).

After this exercise I am more confident that the two resources are in alignment, and that
we can reduce redundancy by editing the wiki as the next step.
