Question - HQMF 2.1 Subsets and ""

[ewhitley]

Hello -

More of a question than an issue.

Some of the new EH measures released in May (EX: "EH_CMS190v4_NQF0372_VTE2/CMS190v4.xml") include excerpt entries that use sequenceNumber - no "subsetCode" entry.

The HQMF 2.x parser seems to want to have a type for these (https://github.com/projectcypress/health-data-standards/blob/7d49e1dd92815dd77b375a918b515c829a3a5a04/lib/hqmf-parser/2.0/types.rb#L183) "@type = attr_val('./cda:subsetCode/@code')"

In reading more of the documentation, there's a note that says "This representation aligns with the HQMF specification and does not require a subset operator."

The Data Criteria parser seems to attempt to create subset_operators for each "excerpt entry"
https://github.com/projectcypress/health-data-standards/blob/7d49e1dd92815dd77b375a918b515c829a3a5a04/lib/hqmf-parser/2.0/data_criteria.rb#L274

In the event that this is a sequence entry and does not contain a subsetCode, should we avoid creating a subset entry? Should the xpath in the data criteria parser only include entries that contain a subsetCode node?

Thank you,
Eric
