From the "Guide to MRML": "The Mind Reading Markup Language (MRML /mur'mul/) is a proprietary extension of the HyperText Markup Language. This document, all MRML tags, and any ideas you come up with while reading this information are the exclusive property of the authors. This is an open specification that will be expanded as mind control technology is refined. MRML tags can be embedded into any regular HTML document. They are completely invisible to all browsers. No one will ever know you are using them."
The <HYPNOTIZE> element has a special post-markup-event constraint (it includes the so-called Brainwashing elements, which enable very primitive mind control): "you are liable for any mental damages inflicted by improperly placed tags."
NOTE: MRML could be used as an XML language, but users will need to stay alert: "MRML is not case sensitive. <freud> is equivalent to <FREUD> or <frEUd>." XML well-formedness requires that case-sensitivity be observed with respect to spelling of element names in each occurrence of start-tag and its (paired) end-tag.
