Hi Vincent,

Thanks as well for checking!

Using the patch attached to make the error a bit more verbose,
I ended up with the following URI:

update-xmlcatalog: error: entity referred by "http://www.w3.org/TR/rdfa-syn=
tax/DTD/xhtml-rdfa-model-1.mod" not registered
update-xmlcatalog: error: entity referred by "http://www.w3.org/2003/entiti=
es/2007/htmlmathml-f.ent" not registered
update-xmlcatalog: error: entity referred by "http://www.w3.org/TR/rdfa-syn=
tax/DTD/xhtml-rdfa-model-1.mod" not registered
update-xmlcatalog: error: entity referred by "http://www.w3.org/2003/entiti=
es/2007/htmlmathml-f.ent" not registered

Those two have in common to be referenced by duplicate systemId
lines in the catalog:

$ nl htdocs/sgml-lib/catalog.xml | grep -C0 'htmlmathml-f.ent\|xhtml-rdfa-m=
odel-1.mod'
   253	  <public publicId=3D"-//W3C//ENTITIES XHTML+RDFa Document Model 1.0=
//EN" uri=3D"REC-rdfa-syntax-20081014/xhtml-rdfa-model-1.mod" />
   254	  <system systemId=3D"http://www.w3.org/TR/rdfa-syntax/DTD/xhtml-rdf=
a-model-1.mod" uri=3D"REC-rdfa-syntax-20081014/xhtml-rdfa-model-1.mod" />
   255	  <system systemId=3D"http://www.w3.org/TR/rdfa-syntax/DTD/xhtml-rdf=
a-model-1.mod" uri=3D"REC-rdfa-syntax-20081014/xhtml-rdfa-model-1.mod" />

   538	  <system systemId=3D"http://www.w3.org/2003/entities/2007/htmlmathm=
l-f.ent" uri=3D"REC-xml-entity-names-20100401/htmlmathml-f.ent" />
   539	  <system systemId=3D"http://www.w3.org/2003/entities/2007/htmlmathm=
l-f.ent" uri=3D"REC-xml-entity-names-20100401/htmlmathml-f.ent" />

I tried to deduplicate both lines just in case, but error
messages remained.  I don't know the root cause I'm afraid.

Any ways, in hope this helps,
