Subject: Replaced function-like data resolution with template applications *
 e.g. article and tag support data is now fetched through direct _XPath_
 template applications ** this required the introduction of a special
 `resolve` mode to prevent interaction between support and main content
 resolution ** in most cases arguments had to be wrapped inside helper
 constants to enable selection of e.g. article support data via the `@handle`
 attribute using the current elements `@handle` attribute * analogously to the
 recent changes in _StaticXSLT_ this commit aims to improve the XSLT code
 style used in generating this static website
