The xml.el output always has an alist for attributes after each tag; if
there are no attributes, the element after the tag name is nil. In
sxml, the `@' denotes an attribute list, which is omitted if no
attributes exist.

It is illogical to criticize sxml for wasting conses, while arguing for
wrapping each text node in a cons.
Anyway, it is difficult to see how real the problem is without a
concrete example. Could you provide one? I suspect that the real
problem, if one exists, is Elisp's relatively weak support for list
mapping and reduction; if that's the case, the correct solution is to
pull in some of the relevant functions from the CL package.
