+<systemitem role="package">docbook-xml</systemitem> provides the
+DocBook XML DTDs, which are commonly used for Debian documentation (as
+is the older debiandoc SGML DTD). This manual, for instance, is written
+in DocBook XML. The <systemitem
+role="package">docbook-xsl</systemitem> package provides the XSL files
+for building and styling the source to various output formats. You
+will need an XSLT processor, such as <systemitem
+role="package">xsltproc</systemitem>, and an FO processor, such as
+<systemitem role="package">fop</systemitem>, to generate documentation.
