setOutputMode(mode)Changes what syntax is used when generating elements. Valid modes are:
PHPTAL::XHTMLIn this mode (which is default) PHPTAL will output XHTML in a way that is backwards-compatible with HTML browsers.
Empty elements will be forced to use self-closing form (<img/>, <link/>), and non-empty elements will always have closing tag.
XHTML output mode changes <link> element in way that is incompatible with RSS. Use XML output mode to generate RSS feeds or use Atom.
Boolean attribtes (checked, selected, etc.) will always have value required by the XHTML specification (it simplifies use of tal:attributes).
<![CDATA[ blocks will be added or removed automatically and will use special escaping syntax that is safe in both XML and HTML.
If you're always sending XHTML as application/xhtml+xml, then it's better to use XML output mode.
PHPTAL::HTML5This mode generates documents that have best compatibility with text/html parsing in current web browsers, but are not XML.
PHPTAL will change DOCTYPEs to <!DOCTYPE html>. Namespace declarations, name prefixes, explicit CDATA sections and other HTML-incompatible constructs will be ommited.
This mode is not a "tag soup". PHPTAL will close all elements properly and quote attributes when it's necesary. Output will be properly formatted HTML 5, and fully backwards-compatible with current HTML 4 browsers.
PHPTAL::XMLThis mode outputs "pure" XML without compatibility with text/html parsing. Use this mode when generating feeds, SVG, MathML, RDF and other XML files.
