As mentioned above, only definitions placed in \verb|header.tex| are global for your entire article. You can use all flavors of \TeX's definitions (\verb|\def|, \verb|\edef|, \verb|\xdef|, \verb|\gdef|, \verb|\newcommand|, \verb|\rewnewcommand|, ...) to your liking.  If you want to discuss a notable \textbf{term}, such as \latexml, you may want to define a handy macro which:  \begin{enumerate} \item Links to the term's Wikipedia page  \item Is available in your entire document (define it in \verb|header.tex|)  \item Flexibly figures out if it needs a trailing space or not\footnote{one of \TeX's original weaknesses with its macros}
