Support for resource templates is missing in pcs. It is not possible to manage resource templates and use them in constraints nor resource creation. Pcs is not able to properly manage resources referencing templates. See Chapter 12. Resource Templates in Pacemaker Explained: http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html-single/Pacemaker_Explained/index.html#_configuring_resources_with_templates
This currently prevents "clufter ccs2pcscmd" emitting pcs commands of how shared fence devices are encoded in CIB during the conversion process right now (not that it cannot be changed, but it is inconvenient at the very least).

Similarly to [bug 1281358 comment 2], this could be worked around using appropriate (currently non-existent) switch to cibadmin until there's a proper support delivered in pcs. Note that unline id-refs, templates are first-class concept, substantially easier to present to the users. Re [comment 1]: One of the options is to implement "template" exploding in XSLT, which could then be reused as a filter in clufter easily, so if the target pcs would be the one that doesn't resolve this bug yet, it would resort to using that filter on the path from CIB to pcs commands.
Templates _do_ get used -- as opposed to other syntanctic extensions (extravagance); see the conclusion of the recent upstream community survey (not very representative but at least some backing numbers): https://lists.clusterlabs.org/pipermail/users/2018-June/015165.html
