  abstract	= {In this paper we investigate the architecture of a MathML
		  formatting engine based on an abstraction of the {\TeX} box
		  primitives. This engine is carefully designed so that the
		  {\TeX}-dependent formatting rules are isolated from the
		  independent ones and is capable of achieving
		  {\TeX}-comparable output quality when used in conjunction
		  with {\TeX} fonts. We show how the formatting rules
		  presented in Appendix~G of the {\TeX}book can be easily
		  adapted for MathML formatting, and how the
		  semantically-rich MathML markup simplifies the rules
		  themselves.}
