1. 6 taxonomy_xml.module \taxonomy_xml_parse_lsid()
2. 7 services/lsid.taxonomy_service.inc \taxonomy_xml_parse_lsid()

Helper function to check if a given string looks like an LSID. If so, it returns it in an array of componant bits. If not, returns NULL.

LSID is a "Life Sciences Identifier" GUID used to identify Taxonomic concepts. It's not great, and it's probably not going to carry on living, but it's out there in metadata and web services.

For convenience, it also returns a namespaced 'type' so we can quickly see what 'type' of resource the LSID is referring to. eg an LSID starting with 'urn:lsid:ubio.org:classificationbank' is the type of entity that Drupal will call a term, and TCS would call a TaxonConcept.
