source: modules/prototype/index.js, line 1

The Prototype module provides a customizable XML transformation layer.

Using the key tag <prototype> you can define a collection of transformation rules based on CSS selectors. The rules cannot modify the tree, transformations are limited to attributes only. You can add, remove and override attributes.

The transformations are applied after the XML tree completes the loading, while smx parsing process. <prototype> tags are removed once they get parsed. No footprints on resultant working XML tree.

You can think of it as CSS for XML attributes, kind of XSLT but using CSS selectors instead of XSLT patterns.

Reserved XML: `<prototype>`.
