Not necessarily in XSLT:
"(...) each GRDDL transformation specifies a transformation property, a 
function from XPath document nodes to RDF graphs. This function need not 
be total; (...) Developers of transformations should make available 
representations in widely-supported formats. XSLT version 1 is the 
format most widely supported by GRDDL-aware agents as of this writing, 
though though XSLT2 deployment is increasing. While technically 
Javascript, C, or virtually any other programming language may be used 
to express transformations for GRDDL, XSLT is specifically designed to 
express XML to XML transformations and has some good safety 
characteristics; XQuery has similar characteristics to XSLT, though use 
of XQuery in GRDDL implementation is less widely deployed at the time of 
this writing. (...) Non-XSLT transforms may indicate the RDF graph in 
some other, unspecified, fashion."
