Coders that care about standards have fixes for the problems they experience with software. It’s relatively easy for a coder to automatically escape ampersands in generated code; at the very least, they know how to Google the fixes. At best, they can scrub all automated output, fix errors, and tune their HTML to a degree most designers would only dream of. And many of these coders look at the designer’s failure to duplicate their success as laziness or worse, without realizing that a designer’s skill set simply does not extend to the world of fixing code output.
[Maar ik moet meer rekening houden hiermee:]
I don’t expect a coder to know the first thing about monitor colour profiles or typography; it’s great if they do, but I don’t expect it. Likewise, a coder should not assume a designer knows how to deal with data, or fix validation errors using code.
