It means that you can manipulate strings, integers, dates, times, etc -
all 44 built-in types - but you cannot attach type annotations to nodes.
So with a Basic XSLT Processor I can do:
<xsl:if test="xs:date(@date-of-marriage) gt xs:date(@date-of-death)">
which takes the string values of two attributes, converts each one to a
date, and then compares them as dates. But I cannot do a date comparison
as:
<xsl:if test="@date-of-marriage gt @date-of-death">
which relies on the schema processor annotating these attributes as
being of type date.
I hope this makes it clearer.
