This carries the risk, however, of perpetuating suboptimal aspects of existing practices, and of failing to grasp opportunities for improvement by declining to introduce a better design. In turn, this creates a long-lasting legacy that becomes difficult to reverse later, thus compounding the problem. While I agree that existing practices can inform the design, they should not be regarded as constraining it. After all, one of the principal purposes of enhancing HTML is to enable and encourage the Web to shift toward semantically richer markup, as a superior replacement for the mess (both syntactically and semantically) that too often occurs today. As user agents and other tools take advantage of this semantic richness, existing practices will change in both foreseen and unforeseen ways. Thus, while knowledge of current practice is informative, there is a danger of its exercising too much of a conservative influence, which must be guarded against in these discussions. Design consistency, having a well defined specification, offering genuine improvements over current markup and providing features that will adequately serve the purposes for which they are introduced, will all encourage adoption. Minor improvements over existing practices may, on the other hand, lead potential implementors to conclude that the additional benefits are not sufficiently great to warrant adoption.
