For the record, this is how to include a "DOCTYPE declaration"n: in Zope when you use "PageTemplates with METAL"n:

In your standard template object (e.g. StandardLook.zpt):

<metal:block define-macro="standard">
<?xml version="1.0"?>
 <metal:block define-slot="doctype">
   <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<html xmlns="" xml:lang="en" lang="en">

This site is not XHTML valid (yet), but W3C has the validator to use.



Thanks for a great bit of advice! I find that some parsers (notably W3C's validator) get a little confused by the empty 1st line that this results in. I fixed it by doing

<metal:block define-macro="foobar"
><?xml version="1.0" encoding="utf-8"?>

instead -- no newline between the end of metal:block and the beginning of the xml processing directive.
