I cannot recommend xmllint in regards to RELAX NG. Unfortunately, I was never
able to validate my DocBook 5 documents against the DocBook RNG schema. ;-(
Better use Jing.

Well, consider this snippet with the same typo than your document (xlink:hef
instead of xlink:href):
<para>This links to the <link
xlink:hef="http://www.docbook.org";>DocBook site</link>.</para>
Validate the XML file which contains the above snippet using this command:
$ jing -c docbook.rnc db5-xlink.xml
That gives me the following error:
db5-xlink.xml:7:40: error: attribute "xlink:hef" not allowed here; expected
attribute "annotations", "arch", "audience", "condition", "conformance",
"dir", "endterm", "linkend", "os", "remap", "revision", "revisionflag",
"role", "security", "userlevel", "vendor", "version", "wordsize",
"xlink:actuate", "xlink:arcrole", "xlink:href", "xlink:role", "xlink:show",
"xlink:title", "xlink:type", "xml:base", "xml:id", "xml:lang", "xreflabel" or
"xrefstyle"
/tmp/db5-xlink.xml:7:40: error: element "link" missing one or more required
attributes; expected attribute "annotations", "arch", "audience", "condition",
"conformance", "dir", "endterm", "linkend", "os", "remap", "revision",
"revisionflag", "role", "security", "userlevel", "vendor", "version",
"wordsize", "xlink:actuate", "xlink:arcrole", "xlink:href", "xlink:role",

"xreflabel" or "xrefstyle"
As you can see, the wrong attribute is indeed reported. The only issue you
have is that xmllint is broken.
The moral of the story: use jing. :)
