Sure, is needed. Checked it again.

I define \scalesetting as

\edef\scalesetting{scale=\xmlattdef{#1}{scale}{1000}}

But I am not sure why this needs the expansion..

The enclosing \rotate[rotation=\xmlattdef{#1}{rotation}{0}]{...} does not need the \expanded.

The exapnsion is need for this part only:

\scale[\scalesetting]

ConTeXt checks if the argument contains an assignment which isn’t the case unless you expand \scalesetting and it sees the = in the argument.
