Lack of support - so posting a documentation issue here...this is required for the processing rules certification exam
1) Please correct/clarify the Processing Rules documentation for "Page Root Domain", I think the second definition (b) is correct:
a) Dimensions Available to Processing Ruleshttps://marketing.adobe.com/resources/help/en_US/reference/processing_rule_dimensions.htmlPage Root Domain - The last two sections of the hostname of the page. http://en.main.example.co.uk/index.jsp?q=value, such as co.uk.
b) Marketing Channel Processing Rules – Definitionshttps://marketing.adobe.com/resources/help/en_US/mchannel/r_channel_rule_definitions.htmlPage Root Domain (TLD+1) - The root domain of the page on which the visitor lands, such as example.co.uk.
2) There is no information on the Context Data variable length.Certification exam implies this is 2k bytes - but where's the documentation?
