concrete5 generates diffent "style" tags. But these are not validating, they are incorrect.

If we follow the correct definition of styles (as described inhttp://www.w3.org/TR/REC-html40/present/styles.html... ) we have to change these files:

/concrete/blocks/form/styles_include.php
/concrete/blocks/form/view.php
/concrete/blocks/google_map/form_setup_html.php
/concrete/blocks/google_map/view.php
/concrete/blocks/guestbook/view.php
/concrete/blocks/page_list/page_list_form.php
/concrete/blocks/rss_displayer/form_setup_html.php
/concrete/blocks/rss_displayer/view.php
/concrete/blocks/search/view.php
/concrete/blocks/search/form_setup_html.php
/concrete/blocks/slideshow/view.php
/concrete/blocks/slideshow/form_setup_html.php
/concrete/blocks/survey/view.php
/concrete/blocks/video/form_setup_html.php
/concrete/blocks/youtube/form_setup_html.php
/concrete/elements/collection_add.php
/concrete/elements/collection_metadata.php
/concrete/elements/collection_theme.php
/concrete/models/block_styles.php
/concrete/single_pages/dashboard/pages/themes/marketplace.php
/concrete/single_pages/dashboard/pages/themes/view.php
/concrete/single_pages/dashboard/scrapbook/view.php
/concrete/single_pages/dashboard/settings/view.php
/concrete/single_pages/dashboard/users/registration.php
/concrete/single_pages/dashboard/jobs.php

in these files we have to replace '<style>' with '<style type="text/css">'

Please can someone do this and add it to SVN / CVS?

Next thing is the following:

Authors should use the META element to set the default style sheet language for a document. For example, to set the default to CSS, authors should put the following declaration in the HEAD of their documents:

<META http-equiv="Content-Style-Type" content="text/css">

So we have to add this content line in standard meta tag output (which is done by /concrete/elements/header_required.php
