+	<target_environments>
+		<html:div>
+			In order to remain current, each Eclipse release targets
+			reasonably
+			current versions of the underlying operating environments.
+			The ATL
+			project depends upon on the Platform and other projects, which
+			are
+			mostly "pure" Java. The 3.5 release of the Eclipse Platform
+			Project
+			is written and compiled against version 1.4 of the Java
+			Platform
+			APIs, and targeted to run on version 1.4 of the Java Runtime
+			Environment, Standard Edition. ATL will target the same Java version
+			as the platform.
+		</html:div>
+		<internationalization>
+			<html:div>
+				The Eclipse Platform is designed as the basis for
+				internationalized
+				products. The user interface elements provided by
+				the Eclipse SDK
+				components, including dialogs and error messages, are
+				externalized.
+				The English strings are provided as the default
+				resource bundles. As
+				a result, the ATL project will provide English
+				strings in its
+				default bundles and be localized to a subset of those
+				locales
+				offered by the Platform. This plan will be updated to
+				indicate which
+				locales will be provided and the time frame for
+				availability.
