Why are developers using XHTML to layout web pages? I don't understand this. XHTML is a great way to standardize code but standardization can also be accomplished using HTML Strict and Transitional DOCTYPES. XHTML is great for web applications but not web pages.
I work in a development firm and in all honesty, 90% of the HTML builders here don't understand or know squat about valid DOCTYPES more or less XHTML. They asked me to build out a site for them; I used HTML Strict as the DOCTYPE. Lo and behold, the other developers are looking at the CSS layout and the DOCTYPE while scratching their heads trying to understand.
I do my best to program using standards but it appears to me that in the real working world, DOCTYPES and Valid markup are not common practice. All these newbies that are learning using XHTML and so proud that their page validates the W3C validator, are missing the big picture in web development. XHTML is a tool to help standardize web development but in my opinion, does not provide the most flexibility for web design. Someone will argue this so feel free to contribute your thoughts.
