Error with "rounded" style and tikz format

[OldKrab]

Dot code:

digraph {
"x" [shape=box, style=rounded]
}

run with cmd:

dot2tex -ftikz example.dot

Got next tex:

\node (x) at (27.0bp,18.0bp) [draw,rectangle,rounded] {x};

% End of code

\end{document}

Tex fails to compile with error "Package pgfkeys: I do not know the key '/tikz/rounded' and I am going to ignore it. Perhaps you misspelled it."

I think instead of [draw,rectangle,rounded] there should be something like [draw,rectangle,rounded corners].

According to customization_guide style attribute used by rendering backend.

So we can not render same dot file that can be rendered with graphviz, because style attribute has different meaning in graphviz.

is this the right behavior?
