      Description

      It would be desirable to support a simplified syntax for obtaining data via bindings and inserting it. A proposal has been to adopt ant-like syntax ("$

      {...}

      ") and interpret the expression within the braces as a binding reference. This would eliminate the need for many Insert components, i.e.:

      <h1>$

      {thread.title}

      </h1>

      rather than:

      <h1><span jwcid="@Insert" value="thread.title"/></h1>

      Or:

      $

      {message:prompt}

      rather than:

      <span key="prompt"/>

      This kind of substitution is less invisible, but generally less intrusive, than creating a new component.

      Further, the use of the Any component could be reduced via support for:

      <img src="$

      {imagePath}

      "/>

      rather than:

      <img jwcid="@Any" src="ognl:imagePath"/>

      Some questions occur; are the following legal?

      <$

      {element}> ... </${element}

      >
      <img jwcid="@Image" src="$

      {asset:foo}

      "/>
      <div $

      {attribute}

      ="$

      {value}

      "/>

      A final note: these bindings should be treated as we treat informal parameters today; this includes automatically expanding IAssets into their corresponding URLs.
