looks like an unfinished coloring state


removing the \setpretty`\: lines in the file verb-xml.tex helps


btw,


\startbuffer
<?xml version="1.0" encoding="UTF-8"?>
<locationURI oeps:oeps="x:x">zip:/?file:////path/to/a.zip</locationURI>
\stopbuffer

\showXMLbuffer

also is an option

if you want the whole verbatim to have one color, don't use option= but 
just use color=...
