Before calling the external Java library I need to set some
attributes, e.g.
pgp.setArmor(true)
pgp.setConventional(true)
pgp.setInputIsText(true)
pgp.setOutputIsText(true)
Is it possible to do this within the style sheet?
Yes, if you're careful. The problem is that these methods don't generate any
output, so there's a risk that they can get optimized away (or called in the
wrong order). The trick is to use them as if they were returning something,
and that something were written to your result tree, for example
<out>
<xsl:value-of select="PGP:setArmor(true()), PGP:setConventional(true()),
PGP: ...etc"/>
Also the XSLT programmers reverence seems to imply that only
static types are supported - is this the case?
No. The behaviour of extension functions varies from product to product and
release to release. The documentation for Saxon 8.9 is at
