All XML documents declare their doctype, referencing a document type definition file. The DTD for SQL repository templates is installed within the <ATG2007.3dir>/DAS/lib/classes.jar archive, but can be referred to with this URL:
http://www.atg.com/dtds/gsa/gsa_1.0.dtd
You should not need to change the reference to the DTD in the following DOCTYPE tag:
<!DOCTYPE gsa-template
PUBLIC "-//Art Technology Group, Inc.//DTD General SQL Adapter//EN"
"http://www.atg.com/dtds/gsa/gsa_1.0.dtd">
Note that if your SQL repository definition is composed from more than one file, using XML file combination, only the file that appears first in the CONFIGPATH should include the DOCTYPE declaration. See XML File Combination in the Nucleus: Organizing JavaBean Components chapter of the ATG Programming Guide.
