Subject: DOCBOOK: e 2.71828
I have a need to include the mathematical constant e, 2.71828..., the base of the natural logarithms, in a book I'm writing. According to the Unicode folks, they have no special character for this and none is needed. I should just use the normal ASCII e. That's simple enough. In typesetting a mathematical constant of this nature is normally italicized so it's not just plain text. How should I represent this in DocBook? <inlineequation>e</inlineequation> is not valid because the inlineequation element can't contain PCDATA. The best I can figure is <inlineequation> <inlinemediaobject> <textobject> <phrase>e</phrase> </textobject> </inlinemediaobject> </inlineequation> which really seems excessively complicated. Going to MathML seems even worse. Is this really the best I can do? -- +-----------------------+------------------------+-------------------+ | Elliotte Rusty Harold | elharo@metalab.unc.edu | Writer/Programmer | +-----------------------+------------------------+-------------------+ | The XML Bible, 2nd Edition (Hungry Minds, 2001) | | http://www.cafeconleche.org/books/bible2/ | | http://www.amazon.com/exec/obidos/ISBN=0764547607/cafeaulaitA/ | +----------------------------------+---------------------------------+ | Read Cafe au Lait for Java News: http://www.cafeaulait.org/ | | Read Cafe con Leche for XML News: http://www.cafeconleche.org/ | +----------------------------------+---------------------------------+
