Register a new argument. Call this method from your ViewHelper subclass inside the initializeArguments() method.
This exists only to throw our own exception!

renderThenChild()
Returns value of "then" attribute.
If then attribute is not set, iterates through child nodes and renders ThenViewHelper. If then attribute is not set and no ThenViewHelper and no ElseViewHelper is found, all child nodes are rendered
protected string
renderElseChild()
Returns value of "else" attribute.
If else attribute is not set, iterates through child nodes and renders ElseViewHelper. If else attribute is not set and no ElseViewHelper is found, an empty string will be returned.
string
compile(string $argumentsName, string $closureName, string $initializationPhpCode, ViewHelperNode $node, TemplateCompiler $compiler)
The compiled ViewHelper adds two new ViewHelper arguments: thenClosure and elseClosure.
These contain closures which are be executed to render the then(), respectively else() case.
