The optimizer in whatever processor you are using may or may not save
you from this by realizing it should cache the results of the doc()
function, but defining a global variable (one a child of the
xsl:stylesheet element)

<xsl:variable name="flaws3" as="document-node()"
    select="doc('../work/flaws3.xml')"/>

and then doing the apply-templates as

<xsl:apply-templates select="@*, node(),
    key('flaws', CatNumbers/@pofis-number, $flaws3)/node()"/>

is likely to get you better performance.
