Actual Results:  
hangs

Expected Results:  
complaing about the lameness of the data, er, displayed the data

This is not Phoenix-specific. The "hang" is due (I believe) to the XSLT
transformation done for pretty-printing.

Perhaps we should not pretty-print very large files, and just prompt for download?

Comment 2

[Benjamin Smedberg]

Oh, and the document is technically invalid XML, because it doesn't contain
<?xml version="1.0"?> at the beginning. But I don't think that affects the
testcase, as it is being served as the text/xml mimetype and being parsed
through the XML parser.
