- // * One-letter tag names and local variable clash problem
- //
- // a at|an|an anc anch
- // b bt|bo|bl bld bold
- // i it|it|it itl ital
- // p pt|pr|pr par para
- // q qt|qu|qt quo quot
- // s st|st|st stk strk
- // u ut|un|un unl undr
- //
- // Other options:
- // - _a, a_, xa
- // - A, I
- // - x::i
- // - user-defined literals: "a"_e, "/a"_e, "id"_a
- //
- // Things can actually get much worse, consider:
- //
- // int i;
- // s << i << "text" << ~i;
- //
- // So perhaps this is the situation where the explicit namespace
- // qualification (e.g., x::p) is the only robust option?
- //
- //
- // * Element/attribute name clash problem (e.g., STYLE)
- //
- // - some attribute/element name decorator (STYLEA, STYLE_A, STYLE_)
- // - rename attribute/element (e.g., STYLEDEF or CSSSTYLE[adds TYPE]);
- // in case of STYLE we should probably rename the element since
- // attribute will be much more frequently used.
- // - "scope" attributes inside elements (P::STYLE); somewhat
- // burdensome: P(P::STYLE); could then use low-case names
- // for attributes
- // - "scope" elements inside other elements (HEAD::STYLE); also
- // burdensome.
- //
- //
- // * Text wrapping/indentation
- //
- // For some (inline) elements we want additional indentation:
- //
- // 1. Indent content on newline (e.g., for <style>).
- // 2. Automatically wrap and indent lines at (or before) certain
- // length, say, 80 characters (e.g., for <p>).
- //
- // Would be nice to be able to implement this at the XHTML level,
- // not XML.
