[xquery-talk] XML serialization of tab and newline

[Paul J. Lucas]

If you look at the the W3C XQuery test K2-Serialization-7.xq:

	<a>{codepoints-to-string(1 to 31)}</a>

the expected result escapes all the characters in the the ASCII range 1-31.

It's not clear why the tab (0x9) and newline (0xA) characters are escaped at since they're perfectly legal in XML files.  Hence, the expected result seems wrong.  Can anybody explain this?
