XMLop{xx} is a shortcut for \XMLpar{list}{xx}{some default}

and as long as the current element is list that will work, so

\defineXMLenvironment[list]
  {here \XMLop{xx} works fine}
  {but here the last element encountered may be another than list}

This works ok here:

\mapXMLvalue {list:packed} {yes} {packed}
\mapXMLvalue {list:packed} {no} {unpacked}

\defineXMLenvironment
    [list]
    [packed=no,setup=1]
    {\startitemize[\XMLop{setup},\XMLval{list:packed}{\XMLop{packed}}{}]}
    {\stopitemize}

\defineXMLenvironment
    [item]
    {\item}
    {\endgraf}

\starttext

\startXMLdata
<list packed='yes'>
    <item>item one</item>
    <item>item two</item>
</list>
\stopXMLdata

\startXMLdata
<list>
    <item>item one</item>
    <item>item two</item>
</list>
\stopXMLdata

\startXMLdata
<list packed='yes' setup='a'>
    <item>item one</item>
    <item>item two</item>
</list>
\stopXMLdata

\startXMLdata
<list setup='a'>
    <item>item one</item>
    <item>item two</item>
</list>
\stopXMLdata

\stoptext

(it may help to look at the x-* files in the context/base path)
