<refpurpose>Calculate an XSL FO table column width specification from a
CALS table column width specification.</refpurpose>

<refdescription>
<para>CALS expresses table column widths in the following basic
forms:</para>

<itemizedlist>
<listitem>
<para><emphasis>99.99units</emphasis>, a fixed length specifier.</para>
</listitem>
<listitem>
<para><emphasis>99.99</emphasis>, a fixed length specifier without any units.</para>
</listitem>
<listitem>
<para><emphasis>99.99*</emphasis>, a relative length specifier.</para>
</listitem>
<listitem>
<para><emphasis>99.99*+99.99units</emphasis>, a combination of both.</para>
</listitem>
</itemizedlist>

<para>The CALS units are points (pt), picas (pi), centimeters (cm),
millimeters (mm), and inches (in). These are the same units as XSL,
except that XSL abbreviates picas "pc" instead of "pi". If a length
specifier has no units, the CALS default unit (pt) is assumed.</para>

<para>Relative length specifiers are represented in XSL with the
proportional-column-width() function.</para>

<para>Here are some examples:</para>

<itemizedlist>
<listitem>
<para>"36pt" becomes "36pt"</para>
</listitem>
<listitem>
<para>"3pi" becomes "3pc"</para>
</listitem>
<listitem>
<para>"36" becomes "36pt"</para>
</listitem>
<listitem>
<para>"3*" becomes "proportional-column-width(3)"</para>
</listitem>
<listitem>
<para>"3*+2pi" becomes "proportional-column-width(3)+2pc"</para>
</listitem>
<listitem>
<para>"1*+2" becomes "proportional-column-width(1)+2pt"</para>
</listitem>
</itemizedlist>
</refdescription>
