Standards are a means to an end
 Interoperability


Standards are sometimes ambiguous
Standards are evolutionary
 CSS 2.0 became CSS 2.1


Internet Explorer 6 shipped in 2001
“Ship or wait for the committee”
Standards can be formalized after you’ve
created your implementation

Ship cycles and Standards don’t always mesh
 Ship now, or ship when the standard is baked?
 What to do when the standard changes?

Then why not ship more often?
 Every standard change, and every bug fix?
 Multiple standards to track
 Increased website updates

Implementing standards is complex
There are many ways to solve a problem
Differences in coding styles can lead to
rendering difference
Different priorities often leads to rendering
differences
First implementation often becomes the
“standard”

Application Formats WG

Every major change to IE run the risk of
breaking existing sites
The Compatibility Conundrum
 How do we move forward with standards while
still pushing the envelope of web technologies?
 Example: increasing the number of XMLHTTP
connections allowed by the browser

Hard to change implementation after you’ve
gone live

“I’m really concerned that we’re breaking
stuff in the name of goodness and that all
users and developers will walk away with is
‘stuff broke’”
