[vox-tech] best way to validate an XML file?

[Brian Lavender]

xmllint recognized if an end tag was missing, but it did not recognize
when I put in an extra attribute such as below. Eclipse recognized it
right away after validating against the schema. The "foo" tag is invalid.

make it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies."
