How to write Macro code for the edit mode?

If you're writing a Macro, and you need to do something specific when the macro is rendered in edit mode, write the following:

• When writing a wiki macro using Velocity

  #set ($targetSyntaxId = $wikimacro.context.transformationContext.targetSyntax.getId())
  #if ($targetSyntaxId == 'annotatedhtml' || $targetSyntaxId == 'annotatedxhtml')
    ... do something specific here ...
  #end

• When writing a Java macro

  public class MyMacro extends AbstractMacro<MyMacroParameters>
  {
      ...
      public List<Block> execute(MyMacroParameters parameters, String content, MacroTransformationContext context)
      {
          ...
          if (Syntax.ANNOTATED_XHTML.getId().equals(context.getTransformationContext().getTargetSyntax().getId())) {
              ... do something specific here ...
          }
          ...
      }
  }

Note that we check for both annotatedhtml and annotatedxhtml because the WYSIWYG editor used to generate Annotated XHTML in the past.
