The following 'markup declaration' could be 'DOCTYPE' or '[CDATA[' (and a couple more).

Quite a lot more.

- "<" means escape from text flow

- If "<" is followed by a "!" it is a standard defined "meta" data item / directive.

(It does make me wonder why the CDATA section 'directive' wasn't just <!CDATA[...]>.  Even more curious, given all the SGML things that got dropped, is how it got included in XML.  It creates just as many problems as it solves.)
