Attribute: xmlns

The xmlns attribute, when added to the sys:job-locations tag, lets the system know which vocabulary to use in evaluating your codes, so that the correct output will be generated.

Should you be aware of the vocabulary that you are using, you can enter the URL of some page that contains a definition of it.

Otherwise, you do not have to include the attribute within the tag at all, and the system will automatically revert to the default vocabulary.

In the end, if you do decide to use the attribute, simply enter the tag into the desired page's "Source" editor window so that it looks something like this:

<sys:job-locations xmlns="http://www.example.org/xhtml" />
