We allow our customer to customize core taglibs (like user-portrait) overriding their jsp's files, but from there you can not retrieve taglib's attributes.

LPS-91526 carried out the first part of these changes, but we need to make public getter methods for those attributes in order to be retrieved from JSP files.
