From my understanding, ContentSlotName should correspond to the template JSP file. Looking into Profile page which is based on AccountPageTemplate, I found that MiniCs a ContentSlotName is not defined in the JSP file. So, I guess it should be in a parent JSP file which includes the template. But I could not relocate the parent JSP file.
FYR, these are files I investigated:
./ext-template/yacceleratorstorefront/web/webroot/WEB-INF/views/responsive/pages/account/accountLayoutPage.jsp
./ext-data/apparelstore/resources/apparelstore/import/coredata/contentCatalogs/apparel-ukContentCatalog/cms-content.impex
After further investigation, I found that ./ext-template/yacceleratorstorefront/web/webroot/WEB-INF/views/responsive/pages/layout/landingLayout2Page.jsp is created based on a parent template called page as defined in .
The template file is ./ext-template/yacceleratorstorefront/web/webroot/WEB-INF/tags/responsive/template/page.tag. This template uses common/header which contains MiniCart inside.
Hopefully, this finding is right.
