defined using a template. The template can use a number of functions; each function has an associated tag. Example: [f0{$1},span class="fbox"] defines a function f0 which corresponds to a span of class fbox, yielding $1. Literal parameters can be used in tags definitions: [f0{$1},span style="color: $p;"] yields $1, where $p is a literal parameter. Sizes can be specified in hybridsizes, e.g. adding parameter sizes. By default the resulting size is the max of all arguments. Sizes are used to generate the right parameters. A function followed by a single / is output as a self-closing XHTML tag: [f0/,hr] will generate
