xpath-axis-completion expression
The following values are allowed:
always, never,
when-empty. Note, that all other values
(including 1) work as never!
If the expression evaluates
to always, TAB completion for
XPath expressions always includes axis names.
If the expression evaluates to
when-empty, the TAB completion list for
XPath expressions includes axis names only if no element name
matches the completion.
If the expression evaluates to
never, the TAB completion list for
XPath expressions never includes axis names.
The default value for this option is
always.
This command is equivalent to setting the
$XPATH_AXIS_COMPLETION variable.
