Re: [xsl] Performance of predicate-based patterns

["Eliot Kimber ekimber@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

The DITA for Publishers Word-to-DITA framework
(https://github.com/dita4publishers/org.dita4publishers.word2dita) has a
generic WordML-to-SimpleML transform
(https://github.com/dita4publishers/org.dita4publishers.word2dita/blob/mast
er/xsl/wordml2simple.xsl). This generates a simplified and generic form of
"word processing markup" from the WordML.

But because it's handling the whole WordML in a generic way it doesn't
have many templates that use predicates, so not sure it helps here.

The intermediate format puts the style name and ID on the element to which
it applies, so the the templates that process that file are either also
simple or are handled within gnarly for-each-group loops that infer
hierarchy from the flat paragraph structures.

This process is also driven by a separately-defined style-to-tag mapping
document, so there's little or no need for templates that match on
variable properties of the input elements.
