Metacat

Background:
Working with Choonhan Youn at SDSC (cyoun@sdsc.edu): they are developing a skin that makes use of the FGDC upload feature included in the SANParks skin. They want to use the ArcCatalog export format that includes the DTD declaration in the XML instance.
Problem:
Metacat was fetching the DTD from the fgdc.gov source, saving it to the local Metacat install, but not successfully registering it in the xml_catalog table.
On subsequent insert attempts, a "file already exists" error was raised and an insert could not continue.
