[Flow] data attributes in Link ViewHelper

[Christian Loock]

Hello,

it seems like it is not possible to use data atrributes with the Link 
ViewHelper:

<f:link.action controller="{tab.controller}" package="{tab.package}" 
action="{tab.action}" data-toggle="tab">

This would lead to an Exception like *#1237823695: Argument 
"data-toggle" was not registered

*However, often when you work with JavaScript (in this caste Twitter 
Bootstraps Tab component), data attributes are a required and convinient 
method to store arbitrary data with dom elements.

Is it planned to add support for data attributes in Links and is there a 
known workarround to get this to work?

Greetings,

Christian
