As per the sling.apache.org document (https://sling.apache.org/documentation/bundles/output-rewriting-pipelines-org-apache-sling-rewriter....) for "Output Rewriting Pipelines" the order property value of the transformer can only be 0 or >0.
But in AEM default pipeline is having order property as -1 (here is the location: /libs/cq/config/rewriter/default).
if somebody have the information regarding order as -1?
It's just processing priority marker,
The highest priority wins.
Code to look at: https://github.com/apache/sling-org-apache-sling-rewriter/blob/master/src/main/java/org/apache/sling...
