#149 skill area needs a way to describe skill level

[David Cramer]

I wanted to use numbers to indicate my skill level, but
needed a place to describe the ranking system, so I
added an optional para as a chile of skillarea:

192c192
< <!ELEMENT skillarea (title, skillset+)>
---
> <!ELEMENT skillarea (title, para?, skillset+)>

Then I could do this:

<skillarea>
<title>Skills</title>
<para>Numbers in parentheses indicate approximate level
of competence for that skill. All rankings are out of a
possible 10.</para>

<skillset>
<title>Languages and Technologies</title>
...

Then I just added <xsl:apply-templates select="r:
para"/> to the r:skillarea template for each format:

<xsl:template match="r:skillarea">
<xsl:call-template name="heading">
<xsl:with-param name="text"><xsl:apply-templates
select="r:title"/></xsl:with-param>
</xsl:call-template>
<xsl:apply-templates select="r:para"/>
<xsl:apply-templates select="r:skillset"/>
</xsl:template>
