That's what I thought.

Perhaps you can tell something from the bash sequence below. That there is no 
debug output from validating the Schema pussles me.

bash-2.05b$ export | grep XML
declare -x XML_CATALOG_FILES="catalog.xml"
declare -x XML_DEBUG_CATALOG="1"
bash-2.05b$ ls catalog.xml
catalog.xml
bash-2.05b$ xmllint --noout --schema lib/catalog.xsd catalog.xml  # Schema

I might add that catalog.xsd is unmodified, just as libxml2. 

However, it do work flawlessly when I run this:

bash-2.05b$ xmlcatalog  catalog.xml http://www.totte.org/NS/Common.xsd

I also tried --debugent but there was no mentionings of catalog files, and it 
tried to load the web URL.

It looks like the catalog isn't activated when xmllint is run. What have I 
done wrong?
