Re: [xsl] What is the relationship between transforming, mapping, and filtering?

["Andre Cusson akhu01@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Filters are foundational.
Everything that exists is a filter.
Filters are the essence of existence and transformation.
Filters transform input to output.
Functions are operational filters.
Mapping is a sequence element filter type.
Reducing and mapping are also filters.
We are filters, so is life, that is all there is.

Functional programming is well grounded in natural logic.
