angularjs - HTML in directive attributes -

Is it a good idea to give the HTML string as a directive in AngularJS? Like:

  & lt; Tile data-content = "& lt; b & gt; some text & lt; / b & gt;" & Gt; & Lt; / Tile & gt;   
 This is just an example, the string will actually be very long and more complex. I'm creating a tile directive that shows a model window with additional content on click I know that it is a string like any other, but I think that is a better way   
 
 
 I recommend that you take a look at this:  
  & lt ; Tile & gt; & Lt; B & gt; Some text & lt; / B & gt; & Lt; / Tile & gt;   
 I would say that it is most suitable  
 Otherwise if the material is dynamic then I will put it in a model and it will pass it to the director. If not, I will pass an identifier for a partial HTML file which will be downloaded and inserted using the service.
