[Qexo-general] problem with document{} constructor

[Daniel Mahler]

document does not seem to handle the usual xml declaration
and/or doctype declaration at the beginning of the document ie:

bash-2.04$ qexo -e '<x/>'
<x />
bash-2.04$ qexo -e 'document {<x/>}'
<x />
bash-2.04$ qexo -e 'document {<?xml version="1.0" encoding="UTF-8" 
standalone="yes"?><x/>}'
<string>:1:12: missing NameSpec
<string>:1:13: missing '}'
<string>:1:13: confused by syntax error
<string>:1:24: node test when focus is undefined
<string>:1:31: confused by syntax error
<string>:1:39: missing expression
<string>:1:48: confused by syntax error
<string>:1:58: missing expression
<string>:1:64: confused by syntax error
<string>:1:65: missing expression
