Does Amara Xslt Processor support Built-in Extension Elements?

[Luis Miguel Morillas]

Old 4Suite Xslt Processor supported Built-in Extension Elements, but
Amara Xslt Processor fails with this xslt stylesheet:
https://github.com/zepheira/amara/blob/master/test/xslt/borrowed/gg_20000722_01.xslt

Processor raises:

XsltRuntimeError: Stylesheet
'file:///home/lm/src/amara/test/xslt/borrowed/gg_20000722_01.xslt',
line 14, column 4, in 'ft:apply-templates': 'No implementation for
extension element 'ft:apply-templates'


Does Amara support extension elements?
