| SAXONICA |
Saxon is distributed in two packages: Saxon-B and Saxon-SA, each of which is available for both the Java and .NET platforms. Saxon-B is available under an open-source license and all its features are available to all users. Saxon-SA requires activation by a license key, and it is possible to purchase various subsets of the functionality. These are summarized in the table below.

Note 1: Extension functions in this category include saxon:try(), which provides
the ability to catch run-time errors; saxon:function() which provides higher-order functions;
saxon:analyze-string() and saxon:for-each-group() which provide XQuery users
with an equivalent to the xsl:analyze-string and xsl:for-each-group instructions
in XSLT; and saxon:index() and saxon:find() which provide a "manual" indexing
capability for XQuery, similar to the xsl:key construct in XSLT.
Note 2: Saxon-B always implements joins using a nested-loop strategy, which takes increasingly
long as the documents become larger. Saxon-SA where possible uses a hash-join algorithm. This applies whether
the join is expressed as a path expression, an XQuery FLWOR expression, or a nested set of xsl:for-each
instructions in XSLT. In some of the queries in the XMark benchmark, the effect is to reduce query time on a
10Mb source document from 16 seconds to 45 milliseconds.
For some of these products, it is also possible for existing users to purchase an upgrade license.
