XML Schema thus provides a form of semantics to the XML document, i.e.
that such element content is to be treated as a decimal number.

Yes - and in your opinion would the following XML snippet:
<ApplicantEstimatedAmount>12.30</ApplicantEstimatedAmount>
provide a form of semantics to the data - i.e. that the data represents
the estimated amount that an applicant requested, given that it occurs
in the context of - for example - a loan application? This added context
would therefore enhance the sematics provided by the
"ApplicantEstimatedAmount" tag to enable it to be interpreted as "the
amount that an applicant requested for a loan".

It doesn't state what units, for example, the number is intended to
represent, e.g. 12.3 froggets, or 12.30 euros.

Yes - but what if it did? For example:
<ApplicantEstimatedAmount
currencyCode="USD">12.30</ApplicantEstimatedAmount>
