itex2MML 1.4.0: Extensible Arrows
We now support extensible arrows,
with LaTeX-style optional arguments.
\xrightarrow[a]{b}
is (in MathML, though not in LaTeX)
equivalent to
\underoverset{a}{b}{\rightarrow}
while
\xrightarrow{b}
is (in MathML, though not in LaTeX)
equivalent to
\overset{b}{\rightarrow}
The supported arrows are
\xrightarrow
\xleftarrow
\xleftrightarrow
\xLeftarrow
\xRightarrow
\xLeftrightarrow
\xleftrightharpoons
\xrightleftharpoons
\xhookleftarrow
\xhookrightarrow
\xmapsto
