I don't see why.  It's just a newer version of the same thing.

If you change the sources to XML and switch to the XSL toolchain, you
don't have to install the DTD or other schema as such, which would
simplify the installation.  But that could already be had with DocBook
4.

The drawback of not having the schema is that you can't verify the
correct structure of the document, and the XSLT processor will just
produce garbage.
