The aim is to typeset a TeX-command given in an attribute on an xml node.
Example

\xmlatt{#1}{style}

where the node has
<node style="\bf"/>
The problem is that this produces the macrotext\bf and does not execute
the \bf.
I guess that the catcoderegime is not that of TeX here.
With what (magical) incantation to do this?
Nb. I know that here I could have coded 'bf" and called with
\csname..\endcsname, but this is but a simple example and would not work
for '\it\bf', etc.
\starttexcode \stoptexcode
Either I am doing something the wrong way, or it isn't that simple. See the example and its output.
