public class Extensions extends Object
To invoke these functions, use a function call of the form prefix:name() where name is the method name, and prefix maps to a URI such as http://saxon.sf.net/net.sf.saxon.functions.Extensions (only the part of the URI after the last slash is important).

Parameters: context The evaluation context arg1 The first sequence to be compared arg2 The second sequence to be compared collation The collation to be used (null if the default collation is to be used) flags A string whose characters select options that cause the comparison to vary from the
standard fn:deep-equals() function. The flags are:
Returns: true if the sequences are deep equal, otherwise false
Parameters: context the evaluation context (supplied implicitly by the call mechanism) doc the document to be released from the document pool
Returns: the document that was released. This allows a call such as select="saxon:discard-document(document('a.xml'))"
Parameters: p1 The first node-set. The iterator must be correctly ordered. p2 The second node-set. The iterator must be correctly ordered.
Returns: true if p1 and p2 contain the same set of nodes
Parameters: in the supplied string
Returns: a sequence of integers, each in the range 0-255, representing the octets of the UTF-8 encoding of the given string
Parameters: context The dynamic context templates The compiled stylesheet source The initial context node representing the document to be transformed
