Hi
To start off, a very brief answer to this:
With the xml & code below I get the following error (from FOP) at
the marked
location:
xsl:with-param is not allowed in this position in the stylesheet!
That is expected. xsl:call-template will result in nodes being created
in the result tree. You cannot use it as a function that returns a
value to pass to another xsl:call-template. XSLT 2.0 would offer
xsl:function for that purpose, but before you run off upgrading the
stylesheet...

My XML can contain optional attributes for tables, things like
border-width,
border-style etc. I need to supply default values if the attribute
does not
exist and as there could be many optional parameters I don't want to
use
XSL:choose statements to cope with the variations.
Instead I'm trying to use a get_params template to see what
parameter is in
question, return the value of the supplied attribute else the
default which
is then used in a with_params statement. The code below is a cludge
to try
and get it working for one attribute (border-style) only.
Strictly speaking, off-topic for the list, but I notice you are
missing out on a very powerful feature of XSLT, called "attribute sets".
You could easily define a set of default attributes for various types
of formatting objects (block, table, table-cell... etc.)
Since you specify the attributes from the explicit values coming from
your source XML directly on the literal result element or via
xsl:attribute, those values will always take precedence over values
that are defined in any applied attribute sets.
Create the desired attribute set as a top-level element in the
stylesheet:
<xsl:attribute-set name="table-border-defaults">
<xsl:attribute name="border">1pt solid black</xsl:attribute>
...
</xsl:attribute>
and a bit further on:
...
<fo:table ...>
<xsl:apply-templates select="@border | @border-style" />
...
<fo:table-body xsl:use-attribute-sets="table-border-defaults">
<xsl:apply-templates select="../@border | ../@border-style" />
...
<xsl:template match="@*">
<xsl:attribute name="name(.)"><xsl:value-of select="." /></
xsl:attribute>
</xsl:template>
The simple template below is probably a bit too generic, but could
prove enough to get you started.
The point is that, if the source table-node contains a "border"
attribute, that one will prevail on the fo:table-body. If not, then
the one from the xsl:attribute-set is used.
