Make it easier to convert @outputclass attribute value to another attribute in PDF output

[raducoravu]

Let's say I want to write a plugin which looks at all DITA elements having a certain @outputclass attribute value and converts them to corresponding XSL-FO attributes. For example convert this:

<p outputclass="float_left">.....

to this:

<fo:block float="left">.....

In the XSLT stylesheet plugins\org.dita.pdf2\xsl\fo\topic.xsl there is a commonattributes template.
I would propose rewriting it to:

<xsl:template name="commonattributes">
  <xsl:apply-templates select="@id"/>
  <xsl:apply-templates select="*[contains(@class,' ditaot-d/ditaval-startprop ')] |
                               *[contains(@class,' ditaot-d/ditaval-endprop ')]" mode="flag-attributes"/>
  <xsl:apply-templates select="@outputclass"/>
</xsl:template>
    
<xsl:template match="@outputclass"/>

so that in my custom XSL I could just override the @outputclass template match and do my thing, generate those corresponding xsl:attributes.
