This question is a follow up to [How to draw inside a TikZ node, using node style?](https://tex.stackexchange.com/questions/11287/how-to-draw-inside-a-tikz-node-using-node-style/45644#45644)

I am trying to get the `AND` and `XOR` gateway from BPMN as seen here <http://www.omg.org/bpmn/Samples/Elements/Gateways.GIF>

As a starting point I found this style file <https://github.com/sbadia/gdeploy/blob/master/francegrilles/tikz-bpmn.sty> but to get the plus and x in the gateway I have to set them as text. That does not look nice at all... How would I draw a thick 'plus' for the `AND` gateway and add the same share rotated by 45° for the `XOR`? With 'thick' I mean that it is significantly thicker than the border of the shape. Also note that neither the plus nor the x actually reach the border of the surrounding shape.
