Re: [xsl] Process map entries in defined order

Hi Gerrit,

How should I know what I thought of last year...? It was interesting to follow
the discussion... and thanks a lot for the suggestion of using an XML
document, I can just keep those <substitute elements>. That is obviously what
I would have chosen with XPath 2.0.

Best regards,
Michael

Did you raise this before? [1]

In XPath 4.0, maps are ordered by default. [2]

BaseX has already rolled out sorted maps, I donC"BBt know when Saxon will
follow.

In the meantime, maybe use an XML document instead of maps?
