### Special tag renderings 

 In a tagrendering, some special values are substituted by an advanced UI-element. This allows advanced features and visualizations to be reused by custom themes or even to query third-party API's. General usage is `{func_name()}`, `{func_name(arg, someotherarg)}` or `{func_name(args):cssStyle}`. Note that you _do not_fcs need to use quotes around your arguments, the comma is enough to seperate them. This also implies you cannot use a comma in your args
