+Note that setting a positive value to

+increase the depth of \textbf{ALchar}, as shown below.
+This is because these parameters are implemented by setting \verb+yoffset+
+field of a glyph node, and this does not increase the depth of the glyph.
+This problem does not apply for \Param{yjabaselineshift}, since

+なお，\Param{yalbaselineshift},~\Param{talbaselineshift}パラメータに

+下の例のように\textbf{ALchar}の深さは増加しないことに注意．
+これは，2パラメータがglyph~nodeの\verb+yoffset+を使って

+\Param{yjabaselineshift},~\Param{tjabaselineshift}パラメータは
