A number of attributes in the PDS common classes have standard value lists. You can look the standard values up in either the Data Dictionary - Abridged document or the Schematron file that comes with the PDS4 master schema. Both can be rather tedious to sort through.
Following are the most commonly used standard value lists for quick reference. They're sorted first by the attribute name, then by the context in which it appears. Many of these appear in several different classes, and the standard value lists depend on which class the attribute appears in, and sometimes - as in the case of <reference_type> - it depends on the containing class one or two levels above that. We'll try to keep these updated as changes and additions propagate to the master schema.
Note that spelling counts - including capitalization and use of underscores vs. blanks. Type these values exactly as they're shown below or you will get a validation error from the Schematron file.

Note: Clearly these values are not sufficient for groundbased data, or indeed anything other than a spacecraft-mounted instrument. Following are some additional fake values we'll use until the above problem is fixed. These values will generate validation errors:
