Markup declarations can affect the content of the document, as passed from an XML processor to an application; examples are attribute defaults and entity declarations. The standalone document declaration, which may appear as a component of the XML declaration, signals whether or not there are such declarations which appear external to the document entity or in parameter entities. [ Definition : An external markup declaration is defined as a markup declaration occurring in the external subset or in a parameter entity (external or internal, the latter being included because non-validating processors are not required to read them).]
For most people, their "childhood self" is the easiest way to identify how they naturally are. The profile is designed to be taken from the earliest recollections you have of yourself. The idea is for you to complete the profile considering yourself before you were influenced by outside factors. We want to identify what your personality was before you felt pressure to be a certain way, learned to value some characteristics more than others, etc. For most people, the easiest way to do that is to think of themselves as a child--before they were really aware of their personalities. If you had a difficult time answering from your childhood perspective, we would recommend that you answer thinking of yourself at a time when you've been most comfortable with yourself--when you felt you were being truest to yourself, instead of acting how outside influences wanted you to act. When answering the questions, think about your very most natural, innate, gut instinct--what would you do if nothing from the outside were influencing your decision.
