Don't use //BBSD_CUST_ACCOUNTS - that searches every element in the
document to see if it is a BBSD_CUST_ACCOUNTS. There is only one such
element, and it can be accessed very quickly as /BBSD_CUST_ACCOUNTS.

The simplest is to write:

<xsl:value-of select="document('BBSC_CURRENCIES.xml')/BBSC_CURRENCIES
                /mappings[CURR_CODE=current()/CURR_CODE]/CURR_ISO"/>

But it would be much more efficient to use a key, as previously
suggested:

<xsl:key name="k" 
         match="/BBSC_CURRENCIES/mappings"
         select="CURR_CODE"/>

and then you can write:

<xsl:variable name="code" select="CURR_CODE"/>
<xsl:for-each select="document('BBSC_CURRENCIES.xml')">
  <xsl:value-of select="key('k', $code)"/>
</xsl:for-each>

The xsl:for-each here isn't iterating, it's just there to establish the
right context node for the key() function.

P.S. What are the eleven exclamation marks supposed to signify?
