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”
ACID2
An attempt to force similar priorities
All browsers try to differentiate themselves
Widgets in Opera
XUL in Mozilla
ActiveX in Internet Explorer
Microsoft DOES care about standards
Active participant in several standards bodies
Cascading Style Sheets WG, Web API WG, Web
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’”
Dean Hachamovitch
General Manager, Internet Explorer Team
Need to balance Standards Compliance with
Site Compatibility
Doesn’t mean don’t improve
We need to be careful
What can you do to increase the power and visibility of your site…
Operating System integration prevents true
Side by Side operation
Frankenstein builds exist, but don’t guarantee
the same behaviour as your users

AddOn’s in Internet Explorer
Introduced in IE6 to improve compatibility
Compatibility is a critical adoption factor
IE7 “Quirks Mode” mostly didn’t change
Standards mode is increasingly popular

2003: 0.5% of top 200 sites use standards mode
A dedicated compatibility team focused on
working with external sites
