Why should browser makers care about standards?
It’s actually very much in their self-interest to have full support for Cascading Style Sheets-1, the Document Object Model (DOM) and XML. Otherwise, developers will continue to shun those new technologies. These are the features that browser makers are counting on to get more people using their latest products. But most developers can’t build sites with these new features, because few clients can afford to pay for the workarounds and multiple versions necessary to cope with incompatible implementations.
