Re: Variables and inherited attributes

[T_MULLEN 58211 6th Singer St <Tom.Mullen@xxxxxxxxxxx>]

I'm new at this so apologies if this is naive but from my recent reading of
the XSLT spec I remembered this:

(excerpt from last paras of 7.6.1)

"The following precedes each procedure element with a paragraph containing
the security level of the procedure. It assumes that the security level
that applies to a procedure is determined by a security attribute on the
procedure element or on an ancestor element of the procedure. It also
assumes that if more than one such element has a security attribute then
the security level is determined by the element that is closest to the
procedure.

<xsl:template match="procedure">
  <fo:block>
    <xsl:value-of select="ancestor-or-self::*[@security][1]/@security"/>
  </fo:block>
  <xsl:apply-templates/>
</xsl:template>

"

>> the currently active value for xml:lang is
>> 
>> <xsl:value-of select="ancestor-or-self::*/@xml:lang[1]"/>
>> 
>Not quite; that select expression returns the set of xml:lang values on
all
>ancestor nodes (the [1] does nothing, as an element can't have two
xml:lang
>attributes), and the xsl:value-of then selects the string value of the
first
>one in document order, which is the outermost.
