Mottos and Optional Semi - parameters in General and for EATS Reinhard

Motto texts will cause some logical and practical difficulties, when they are to be prefixed to chapter headings. To solve them, the motto text should be specified after the chapter heading. To allow for a variety of contained constructs such as footnotes or verbatims, this text must not be read as an ordinary parameter. These antagonistic goals are reconciled in a construct which looks like a parameter but is treated as input text. This concept is a modified version of the technique used for PLAIN footnotes. We give all macros necessary to implement this concept as an extension to UT$.
