RFC 5261, "An Extensible Markup Language (XML) Patch Operations Framework Utilizing XML Path Language (XPath) Selectors", September 2008

Section 8 says:

<!ENTITY id     "id\(('&ncname;')?\)|id\((&quot;&ncname;&quot;)?\)">

It should say:

<!ENTITY id     "id\('&ncname;'\)|id\(&quot;&ncname;&quot;\)">

Notes:

The regex in the XSD suggests that "id()" would be a valid selector for a patch, but it would not make sense to specify such a selector since it never would select a node (there's no identifier to locate in the document). This means that while "id()" is a valid XPath expression, it should not be allowed as a selector expression within an XML patch document.
