ConTeXt fontsizing has \tx to make the current font style one step smaller, then another \txx does that again. For makeing the size bigger I cannot see anything other than the series \tfa \tfb \tfc \tfd. It would however be nice to also have a similar cumulative effect here.
Can there be something like "\tsmall" available to reduce the font size one step (to a certain minimum, not just \tx\tx = \txx)? And similar \tbig to enlarge the font size one step? It will make the equivalent of HTML's <small> and <big> tags easy to implement for typesetting my xml data.
Or are there already such things? \startxmlsetups big \bgroup \switchtobodyfont[\the\dimexpr\bodyfontsize+2pt\relax]
\switchtobodyfont[\the\dimexpr\bodyfontsize+\xmlattdef{#1}{step}{2pt} \relax]
\xmlflush{#1} \egroup \stopxmlsetups
\startxmlsetups small \bgroup \switchtobodyfont[\the\dimexpr\bodyfontsize-2pt\relax]
\scratchdimen=\the\dimexpr\bodyfontsize\relax \advance\scratchdimen-\xmlattdef{#1}{step}{2pt}\relax \ifdim\scratchdimen<\xmlattdef{#1}{min}{4pt}\relax\scratchdimen= \xmlattdef{#1}{min}{4pt}\fi \switchtobodyfont[\the\scratchdimen]
\xmlflush{#1} \egroup \stopxmlsetups
