I made fresh installation of springsource-tool-suite-2.1.0.SR01-e3.5-win32-installer.exe and found what there is no XSL tools and XPath tool (if I open XML prespective). There was no problem with version 2.1.0.RC1 (eclipse 3.5 based).
If I open Plug-in Dependencies view and focus on "org.eclipse.wst.xsl.core" - I can see what there is problem with "org.apache.xalan" bundle. This bundle is absent in "plugins" folder, but if I put this bundle from RC1 it did not solve problem.
