POM validation

To validate a POM against its schema, we can use a one-liner combination of:

xmllint (which identifies which element, if any, is invalid);
xmlstarlet (which allows us to extract the schema attribute);
GNU grep (which allows us to extract the XSD's URL from the schema attribute):

xmllint --noout --schema $(xmlstarlet sel -t -v "/_:project/@xsi:schemaLocation" -n pom.xml | grep -o 'http[^ ]*.xsd') pom.xml
