Forward port 7.9 - HST News Sitemap Component - does not parse propertyCriteria property correctly

I am trying to use "propertyCriteria" property in sitemap for News Sitemap from Hippo Forge Sitemap Protocol Component[1]. Parameters that contains colon (:) symbol in parameter name can not be parsed - we get error message in the log "org.hippoecm.hst.core.component.HstComponentException: Criterion does not match pattern "property=condition" ".
Parameter from documentation example[2] also does not work (hippostd:state=published).
It seems that the problem is in org.onehippo.forge.sitemap.components.NewsSitemapFeed.java (line207) where regular expression for matching cafeterias is stored:
Pattern propertyCriterionPattern = Pattern.compile("(\\w)\\s=\\s(
w)"); [3]
