That's true.

I know. However, you need to insert your font somewhere, so the font-family 
attribute maps to a font type.

Well, I guess it's a configuration issue. If you really want to use the 
aequivalent to Times, Helvetica, and Courier, I've found a comment in the 
"fop.xconf" file:

-----------
      <fonts>
        <!-- embedded fonts -->
        <!--
        This information must exactly match the font specified
        in the fo file. Otherwise it will use a default font.

        For example,
        <fo:inline font-family="Arial" font-weight="bold" font-style="normal">
            Arial-normal-normal font
        </fo:inline>
        for the font triplet specified by:
        <font-triplet name="Arial" style="normal" weight="bold"/>

        If you do not want to embed the font in the pdf document
        then do not include the "embed-url" attribute.
        The font will be needed where the document is viewed
        for it to be displayed properly.

        possible styles: normal | italic | oblique | backslant
        possible weights: normal | bold | 100 | 200 | 300 | 400
                          | 500 | 600 | 700 | 800 | 900
        (normal = 400, bold = 700)
        -->

        <!--
        <font metrics-url="arial.xml" kerning="yes" embed-url="arial.ttf">
          <font-triplet name="Arial" style="normal" weight="normal"/>
          <font-triplet name="ArialMT" style="normal" weight="normal"/>
        </font>
        <font metrics-url="arialb.xml" kerning="yes" embed-url="arialb.ttf">
        <font metrics-url="arialb.xml" kerning="yes" embed-url="arialb.ttf">
          <font-triplet name="Arial" style="normal" weight="bold"/>
          <font-triplet name="ArialMT" style="normal" weight="bold"/>
        </font>
        -->
      </fonts>

It seems to me, you need to remove the XML comment before <font metrics-url> 
and add the path to the Arial TTF file. Same with the other two font types.

I haven't tried it out, but it could work. The other solution would be to use 
a totally different font. In that case you have probably more glyphs available 
than Arial or some Helvetica clone.
