[xsl] doc-available vs. exists(document)

[<mlcook@xxxxxxxxxx>]

In the template below, I'm getting different results depending on which "when"
test I use.

If I use the exists(document($name)) test, it passes; but doc-available($name)
fails.

The input document is schema valid.

The template is invoked with something like:
<my-doc href="Initialization\Begin.xml"/>

I thought I was using doc-available correctly, and it has worked fine in other
situations.  I'd like to use doc-available to avoid the java error message
about a file not found, and process the error condition myself.

What am I overlooking?

Thanks, Mike


    <xsl:template match="my-doc">
        <xsl:variable name="name" select="@href"/>
        <xsl:choose>
            <xsl:when test="exists(document($name))">
            <!-- <xsl:when test="doc-available($name)"> -->
                <xsl:message>document is available</xsl:message> 
                <xsl:apply-templates select="document($name)/*"/>
            </xsl:when>
            <xsl:otherwise>
                <xsl:message>document error</xsl:message>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>
