Hi,

Two difficulties in exporting to html5:


1. With the current master branch, some in-buffer settings are ignored:
#+TITLE: Trying to export to html5
#+DESCRIPTION: this won't appear in the exported document...
#+KEYWORDS: html5 exporter meta
#+HTML_DOCTYPE: html5
#+AUTHOR: me
is exported to
<!DOCTYPE html>
<html>
<head>
<title>Trying to export to html5</title>
<meta  charset="utf-8">
<meta  name="generator" content="Org-mode">



<style type="text/css">

This problem is not present in maint (8.0.7) (but neither is the html5 doctype):
<?xml version="1.0" encoding="utf-8"?>
html5
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<title>Trying to export to html5</title>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
<meta name="generator" content="Org-mode"/>
<meta name="author" content="me"/>
<meta name="description" content="this won't appear in the exported document..."/>
<meta name="keywords" content="html5 exporter meta"/>
<style type="text/css">


2. Is the after-export hook gone with the new exporter framework? I used this to get the list of a project's exported files:
(setq html-files-list ()
          org-publish-after-export-hook
          (lambda () (add-to-list 'html-files-list
                                  (buffer-file-name (current-buffer)))))
(org-publish the-org-project t)
(print html-files-list)
but in 8.0.7 maint the hook is ignored altogether.



Best regards,
Daniel
